Jesus paid with His Life to redeem us. He was beaten, mocked, struck, pierced, crucified and killed so that the wages of our sin could be paid by Him, the sinless God. He willingly sacrificed His Life. And for all who believe in Him (i.e., those who have life), the only thing that would be a fair exchange in paying Him back would be a sacrifice of our life as well.

How are you and how am I in our exchange with Jesus Christ. Are we fair?

Galatians 2:20 (KJV)
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.
