“Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, I press toward the mark for the prize of the high calling of God in Christ Jesus.” (Philippians 3:13-14)
There are two days that can steal your joy and the fulfillment of today. One is tomorrow and the other is yesterday. Both are days in which we as Christians should refuse to live.
So many of us have never learned how to separate ourselves from yesterday. We are still dragging it around with us and it is stealing our joy. Paul could have lived there in the realm of guilt, but he refused.
