John 3:1-8New International Version - UK (NIVUK)
Jesus teaches Nicodemus
3 Now there was a Pharisee, a man named Nicodemus who was a member of the Jewish ruling council. 2 He came to Jesus at night and said, ‘Rabbi, we know that you are a teacher who has come from God. For no one could perform the signs you are doing if God were not with him.’
3 Jesus replied, ‘Very truly I tell you, no one can see the kingdom of God unless they are born again.[a]’
4 ‘How can someone be born when they are old?’ Nicodemus asked. ‘Surely they cannot enter a second time into their mother’s womb to be born!’
5 Jesus answered, ‘Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. 6 Flesh gives birth to flesh, but the Spirit[b] gives birth to spirit. 7 You should not be surprised at my saying, “You[c] must be born again.” 8 The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.’[d]
Romans 8:1-11New International Version - UK (NIVUK)
Life through the Spirit
8 Therefore, there is now no condemnation for those who are in Christ Jesus, 2 because through Christ Jesus the law of the Spirit who gives life has set you[a] free from the law of sin and death. 3 For what the law was powerless to do because it was weakened by the flesh,[b] God did by sending his own Son in the likeness of sinful flesh to be a sin offering.[c] And so he condemned sin in the flesh, 4 in order that the righteous requirement of the law might be fully met in us, who do not live according to the flesh but according to the Spirit.
5 Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. 6 The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. 7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. 8 Those who are in the realm of the flesh cannot please God.
9 You, however, are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ. 10 But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life[d] because of righteousness. 11 And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of[e] his Spirit who lives in you.
