I can do all things through Christ who strengthens me. ( Philippians 4:13 NKJ )

And He said to me, “My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me.( 2 Corinthians 12:9 NKJ )

“In returning and rest you shall be saved;
In quietness and confidence shall be your strength.” ( Isaiah 30:15b NKJ )

 Now to Him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, ( Ephesians 3:20 NKJ )

But those who wait on the Lord
Shall renew their strength;
They shall mount up with wings like eagles,
They shall run and not be weary,
They shall walk and not faint. (Isaiah 40:31 )
