We say…

That isn’t one of my strengths.  That is not what I am good at.  I feel that I don’t have what it takes.  

God says…

 Now may the God of peace—who brought up from the dead our Lord Jesus, the great Shepherd of the sheep, and ratified an eternal covenant with His blood- may He equip you with all you need for doing His will. May He produce in you, through the power of Jesus Christ, every good thing that is pleasing to Him. All glory to Him forever and ever! Amen. 

Hebrews 13:20-21
