There is no challenge in the Christian life but that a look to the cross won’t give you a fresh start.
For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds.—Hebrews 12:3
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.—Galatians 2:20
