He Placed The Holy Spirit In Us - 1 Corinthians 15.

2 Corinthians 1:20-22 For all of God’s promises have been fulfilled in Christ with a resounding “Yes!” And through Christ, our “Amen” which means “Yes” ascends to God for his glory. It is God who enables us, along with you, to stand firm for Christ. He has commissioned us, and 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.
