Galatians 2:20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
When we believe in Christ our lives are crucified and risen with Him. Our old life is taken away at the cross and a new life is given. Now you can say, "Jesus Christ lives in me." That’s thrilling.
2 Corinthians 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
How is the life that you now live? Christ gives us a new desire for holiness, for God and for heaven. It‘s not that we can’t sin again; we can. But we don’t want to. The whole attitude of our life has been changed. Christ in the Christian is the hope of glory!
1 John 4:4 Greater is He that is in you, than he that is in the world.
