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.
