The apostle Paul wrote this in a letter. He was revealing a spiritual reality, the results of God’s sacrifice. The life of faith.
“I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.” (Galatians 2:20 NASB)
Can you say, “Me too”? Faith is not all about casting mountains into the sea, or commanding demons to flee. Faith is Christ living in you because you died with Him.
