What is the biblical support for being 'born again' (or' born from above') in this life?

Many think they are 'born again' when they are baptised on receiving the Holy Spirit as a gift from God. However, it seems apparent from the scriptures that being 'born from above' happens at our transformation at Christ's return. In this life we are given a 'deposit', a 'pledge', a 'guarantee' only. >And God has prepared us for this very purpose and has given us the Spirit as a pledge of what is to come. 2 Cor 5:5 >he has identified us as his own by placing the Holy Spirit in our hearts as the first installment that guarantees everything he has promised us. 1 Cor 1:22 >Don't be astonished that I told you, 'All of you must be born from above.' John 3:7 >Flesh is born of flesh, but spirit is born of the Spirit. John 3:6 >unless someone is born again he cannot see the kingdom of God.” John 3:3 >flesh and blood is not able to inherit the kingdom of God, nor does decay inherit immortality. 1 Cor 15:50 ( 'born from above' is the translation commonly rendered 'born again') What scripture supports being 'born from above' in this life?
