Philippians 3:12,Not that I have already attained or am already perfected; but I press on, that I may lay hold of that for which Christ Jesus has also laid hold of me. 13 Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, 14 I press toward the goal for the prize of the upward call of God in Christ Jesus. 

 Isaiah 43:18-19, Do not remember the former things, Nor consider the things of old. Behold, I will do a new thing, Now it shall spring forth; Shall you not know it? I will even make a road in the wilderness And rivers in the desert.
