Read John 3:1-15

Jesus replied, “I assure you, no one can enter the Kingdom of God without being born of water and the Spirit. Humans can reproduce only human life, but the Holy Spirit gives birth to spiritual life.
– John 3:5-6 (NLT)

If our faith is based more on trusting in how well we can obey God, we are doomed to failure. Being born of water and the spirit involves letting God create spiritual life in us, and trusting in God to be faithful to His promise to live in us now and give us life for all eternity.
