Are you born again?
It doesn’t matter who you are no work can save you.
Only born again people can be saved.
The point is that the wind can be neither controlled nor understood by human beings (remembering of course that this was written before modern meteorology alleviated at least some of our lack of understanding). But that does not mean we cannot detect the wind’s effects. We hear its sound, watch the swaying grasses, see the clouds scudding by, hide in fear before the worst wind storms. So it is with the Spirit. We can neither control him nor understand him. But that does not mean we cannot witness his effects. Where the Spirit works, the effects are undeniable and unmistakable.
How is this relevant to the nature of the new birth? Having drawn the implicit analogy through the ambiguous term ‘wind/spirit’, Jesus applies it to the new birth by creating a further explicit analogy: So it is with everyone born of the Spirit. The person who is ‘born of the Spirit’ can be neither controlled nor understood by persons of but one birth. As the ‘water and spirit’ birth is grounded in Ezekiel 36:25–27 (cf. notes on v.5), so there may be an allusion here to Ezekiel 37. There God’s breath/Spirit (rûaḥ/pneuma) comes upon the valley of dry bones and the dry bones are revived; God’s people come to life. Thus it is with everyone born of the Spirit: they have their ‘origin and destiny in the unseen God’ (Fenton, p. 54), not in ‘human decision or a husband’s will’, for they are ‘born of God’ (1:13). Both the mysteriousness and the undeniable power of the Spirit of God are displayed in the Scriptures to which Nicodemus had devoted so many years of study
