Romans 12:2 – NKJV
2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
John 7:37-39 – NKJV
37 On the last day, that great day of the feast, Jesus stood and cried out, saying, “If anyone thirsts, let him come to Me and drink. 38 He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water.” 39 But this He spoke concerning the Spirit, whom those [a]believing in Him would receive; for the [b]Holy Spirit was not yet given, because Jesus was not yet glorified.
