The Spirit Himself bears witness with our spirit that we are children of God. (Romans 8:16, NKJV)
The Spirit bears testimony concerning who is a child of God by means of the truth He revealed and inspired. We have that testimony today in the form of the Holy Scriptures. Our spirit agrees with the Spirit’s testimony when we believe and conform to the truth of the gospel He gave us. For an example of this, see Acts 19:1-5, where some disciples of John did not know of the baptism of Jesus. They had received John’s baptism, but they were not yet followers of Jesus. Paul inspired by the Holy Spirit, taught them of Jesus Christ. “When they heard this, they were baptized in the name of the Lord Jesus” (Acts 19:5). Now, the Spirit’s testimony agreed with their testimony that they were children of God. Before they heard the Spirit’s testimony, believed it and were baptized, although they thought they were saved, the Spirit said otherwise. To be sure you are a child of God, your belief and obedience must agree with what the Spirit says about becoming a child of God. Listen to what the Spirit has said: “For you are all sons of God through faith in Christ Jesus. For as many of you as were baptized into Christ have put on Christ” (Galatians 3:26-27). Are you a child of God? The Spirit bears witness that you are, when you have believed and been baptized into Christ.
4 Then he fell to the ground, and heard a voice saying to him, “Saul, Saul, why are you persecuting Me?” 5 And he said, “Who are You, Lord?” Then the Lord said, “I am Jesus, whom you are persecuting. It is hard for you to kick against the goads.” 6 So he, trembling and astonished, said, “Lord, what do You want me to do?” Then the Lord said to him, “Arise and go into the city, and you will be told what you must do.” (Acts 9:4–6, NKJV)
The appearance of Jesus to Saul the persecutor of Christ brought this violent unbeliever to faith that Jesus was alive. Saul, who had been “breathing threats and murder against the disciples of the Lord,” now yields his will completely to the will of Jesus: “Lord, what do You want me to do?” Saul would be told what to do in the city of Damascus. After three days of prayer and fasting, Jesus sent the preacher Ananias to him, who told him what to do: “And now, why are you waiting? Arise and be baptized, and wash away your sins, calling on the name of the Lord” (Acts 22:16). The vision did not wash away his sins. Three days of prayer and fasting did not wash away his sins (Acts 9:9, 11). Water baptism washed away his sins (because the sinner is baptized into Christ’s death, where His saving blood is applied to sins, Romans 6:3). Do not kick against the goads, and refuse water baptism to wash away your sins. It is what Jesus says you must do, too (Acts 2:38; 1 Peter 3:21).
8 But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith which we preach): 9 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. (Romans 10:8–10, NKJV)
The “word of faith” was preached by the apostles. It produces faith in the good and honest heart (Romans 10:17; Luke 8:15). It produces belief in the heart that God raised Jesus from the dead, and that Jesus is Lord. A verbal confession of one’s faith that Jesus is Lord (Ruler, Master), and that He was raised from the dead, is necessary to be saved. Confessing one’s belief that Jesus is the risen Lord is not the only thing essential to be saved. The command to repent of sins must be obeyed, or we will perish (Luke 13:3, 5; Acts 17:30). Water baptism is also commanded to be saved (Mark 16:16; Acts 10:47-48; 1 Peter 3:21). The “word of faith” contains all these essential actions of faith to be saved by grace. The gospel plan of salvation is for the lost to hear the gospel, to believe in Jesus, the resurrected Lord (the Son of God), to confess Jesus as Lord, to repent of your sins, and to be baptized into Christ. God will save you by His grace, when you do the things God wants you to do.
37 Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, “Men and brethren, what shall we do?” 38 Then Peter said to them, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit. (Acts 2:37–38, NKJV)
In answer to the question posed by the murderers of Jesus (Acts 2:36), Peter did not tell them to “just accept Jesus as your personal Savior, and you will be saved.” (They evidently already believed Jesus to be “both Lord and Christ,” because they are convicted of their sin against Him. You cannot be convicted about something you do not believe.) Peter did not tell them to “pray the sinner’s prayer” to be saved. (Yet, that is what many tell sinners to do about their sins.) Peter did not tell them, “There is nothing you can do to save yourselves. God has done everything.” (But, many tell sinners they are completely passive in their salvation.) Peter did tell them to repent. These believers were not yet saved; they needed to repent, or they would not be saved. Peter also told them to be baptized “for the remission of sins.” Just as one must believe and repent to be saved, one must also be baptized to be saved. Instead of accepting doctrines that deny and oppose this simple passage about how to be saved, why not believe it, obey it, and be saved? When you believe, repent and are baptized, God will remove your sins, just like He did theirs.
12 that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world. 13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. (Ephesians 2:12–13, NKJV)
The Gentiles were not in a covenant relationship with God through the Law of Moses. Only Israel was under that law, and were the people of the covenant (Deut. 5:2-3). That is why Paul speaks of the Gentiles as “having no hope and without God in the world” (v. 12). This is an apt description of the spiritual status of all who are lost in sin: Aliens, without God, without hope, and without an inheritance (see Eph. 2:1-3). But, “in Christ Jesus” all that changes. In Christ, one has a living hope (1 Pet. 1:3). In Christ, the sinner is a new creation (2 Cor. 5:17). Through faith in Christ Jesus, lost sinners are saved, and become children of God (Gal. 3:26; 4:5-7). The alien sinner comes into a saved relationship with God by putting on Christ, which occurs when the sinner is “baptized into Christ” (Gal. 3:27). The blood of Christ – His death for our sins – makes it possible for us to be reconciled to God (Eph. 2:16). It washes away our sins when we are baptized into Christ (Rom. 6:3-4; Acts 22:16). No longer live without God and without hope. By faith, be baptized into Christ and be saved. “Why are you waiting?” (Acts 22:16)
For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit. (1 Corinthians 12:13, NKJV)
There is much disagreement and misunderstanding about the work of the Holy Spirit in salvation. This verse will remove some of that misunderstanding – if we will allow it. The Holy Spirit guided the apostles into “all truth” (the gospel), which they preached to the world (Jno. 16:13; Mk. 16:15). This Spirit-given truth calls upon every sinner to believe, repent and be baptized to be saved (Mk. 16:16; Acts 2:38, 41). Thus, by the direction of the Holy Spirit, all Christians have been baptized into “one body” (the church, Acts 2:41, 47). Based upon this truth, Paul makes a plea for all the members of the church to work together in unity. He notes that one Spirit has directed our baptism in water (by the gospel He revealed), and by doing so, every Christian is a member of the body (church) of Christ. We have all drunk of the spiritual blessings given us by “one Spirit.” The Holy Spirit gives a wonderful gift to all who have been saved – spiritual refreshing and “an inheritance among all those who are sanctified by faith” (Acts 2:38; 3:19; 26:18). Because there is “one body” (the church) and “one baptism” (water), Christians must keep the unity of the Spirit, and not be divided (Eph. 4:3-5).
35 Then Philip opened his mouth, and beginning at this Scripture, preached Jesus to him. 36 Now as they went down the road, they came to some water. And the eunuch said, “See, here is water. What hinders me from being baptized?” (Acts 8:35–36, NKJV)
This passage is particularly instructive about what it means to preach Jesus. Preaching Jesus identifies Him as the suffering Servant of God who sacrificed His life (Acts 8:32-34; Isa. 53:7-8). It includes teaching about sin and salvation from it. The Ethiopian was lost, and wanted to be saved. The water would facilitate his salvation. When he asked Philip about baptism, he had not yet announced his personal faith in Jesus, since Philip stated that as the condition upon which he could be baptized (v. 37). To preach Jesus means preaching baptism, since the Ethiopian immediately asked about it when he saw water. How else did he know about baptism, expect that Philip spoke of it when he “preached Jesus” to him? Surely, he told the man what Jesus preached about baptism: “He that believes and is baptized will be saved” (Mk. 16:16). The Ethiopian confessed his personal faith, stopped the chariot, and Philip baptized him (Acts 8:37-38). The man joyfully went on his way, because he was saved when he believed and was baptized. Christ continues to save sinners the same way, today. What hinders you from being baptized to be saved?
