John 3:36

‘He who believes on the Son has eternal life. But he who does not obey the Son will not see life, but the wrath of God abides on him.'

Not to listen to the Son is dangerous indeed. ‘He who believes on (believes into) the Son has eternal life, ‘the life of the coming age', spiritual life, immortal life. He who does not obey the Son will not see such life, but God's divine anger will rest on him with its consequent results. Notice that believing and obeying are used synonymously. Those who believe will always obey, although belief precedes obedience, and lack of obedience indicates lack of faith. The believer has God abiding in him (John 14:17; John 14:23). In contrast the non-believer does not obey God and has God's wrath, and the results of that wrath, abiding on him. God's wrath is not anger as we know anger. It is not because He cannot control His feelings. The word is describing His total antipathy to sin and all that sin involves, expressed by judgment on that sin and on the sinner. It is thus steady and unchanging unless the sin is atoned for through the means that He has provided. God's antipathy to sin cannot cease. What was therefore necessary was to deal with that sin in such a way that it could be removed as being a hindrance to man's relationship with God.

Note that the last part of this passage had moved from Jesus' Messiahship to His Sonship. Jesus is being revealed as ‘the Christ, the Son of God'.
