The Cross: Crucified with Christ, and Christ Alive in Me

I am crucified with Christ; nevertheless I live; yet not I, but Christ lives 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. - Galatians 2:20
I want to tell you what perhaps the greatest Christian who ever lived (the Apostle Paul) thought of the cross of Christ. Believe me, the cross is of deepest importance. This is no mere question of controversy; this is not one of those points on which men may agree to differ and feel that differences will not shut them out of heaven. A man must be right on this subject, or he is lost forever. Heaven or hell, happiness or misery, life or death, blessing or cursing in the last day - all hinges on the answer to this question: "What do you think about the cross of Christ?"
Let me show you:
1. What the apostle Paul did not glory in.
2. What Paul did glory in.
3. Why all Christians should think and feel about the cross like Paul.
