44 Then Jesus cried out and said, “He who believes in Me, believes not in Me but in Him who sent Me. 45 And he who sees Me sees Him who sent Me. (John 12:44–45, NKJV)
You may think Jesus always spoke in a soft, unassuming voice. If so, you would be mistaken. Many times, He loudly proclaimed His message. He explained that He did not originate His teachings, they came from Him who sent Jesus to the world (John 8:26-30). Jesus spoke what the Father commanded Him to speak (John 12:49). In this sense, He is the Apostle of our confession (Hebrews 3:1). So, to believe in Jesus is to believe in the Father. One cannot believe in God the Father and simultaneously reject Jesus as the Son of God. Jesus has seen the Father and declared Him to the world (John 1:18). Indeed, Jesus shares the same divine nature as the Father. He and the Father are one in nature and purpose, perfectly united in their deity and all that entails (John 10:30). The Son is the image of the invisible God, the exact image of God’s real nature (Colossians 1:15; Hebrews 1:3). No doubt this explain Christ’s amazement when Philip said, “Lord, show us the Father, and it is sufficient for us.” Jesus said to him, “Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, ‘Show us the Father?’” (John 14:8-9). You must look at Jesus and believe in Him to see and believe in God. After all, Jesus is Immanuel (“God with us”).
Most assuredly, I say to you, he who receives whomever I send receives Me; and he who receives Me receives Him who sent Me. (John 13:20, NKJV)
These reassuring words of Jesus, spoken to His apostles, establish the vital importance of following the apostles’ doctrine today. Th word “apostle” means one who is sent. Jesus told them, “As the Father has sent Me, I also send you” (John 20:21). In their case, Jesus sent His apostles into the world to preach the gospel (Mark 16:15). Only by receiving Jesus does a person receive God into his or her life. But, to receive Jesus Christ, one must receive His apostles. Therefore, one cannot reject the apostles’ teachings and rightfully claim to have received Jesus into his life. Receiving the apostles begins by hearing and believing their words (Acts 2:22, 36-37). It continues by obeying their commands (approved by the authority of Jesus) to repent and be baptized for the remission of sins (Acts 2:38-41, esp. v. 41). Furthermore, one then steadfastly continues “in the apostles’ doctrine” (Acts 2:42). Christians continue to learn and follow the word of Christ which His apostles taught. Do you receive Christ’s apostles, by believing and obeying their teachings? If so, you are receiving Jesus and the Father, who sent Him to the world.
He who hears you hears Me, he who rejects you rejects Me, and he who rejects Me rejects Him who sent Me. (Luke 10:16, NKJV)
When Jesus sent seventy of His disciples ahead of Him to be laborers in God’s harvest of souls, they healed the sick and preached, saying, “The kingdom of God has come near to you” (Lk. 10:9). The miracles they worked validated or confirmed the message they preached as being from heaven and not the message of mere men. By receiving their message, people were receiving a message that came from heaven. Today, God speaks to us in His Son (Heb. 1:2). Not by dreams, intuition, whispers or feelings, but through the words of His chose representatives (apostles) whom He sent into the whole world, preaching His gospel (Mk. 16:15). Their message has been validated by miracles (Mk. 16:17-20). Those who believe their word, repent and are baptized to be saved (Mk. 16:16; Acts 2:37-41). Do not reject the gospel of the apostles. To do so means you are rejecting Jesus, the Son of God, and God the Father who sent Him.
