“That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;”
Ephesians 3:16 KJV
It is God that girdeth with strength, and maketh our way perfect. So wait on the LORD: be of good courage, and He shall strengthen thine heart: wait, I say, on the LORD. Be of good courage, and He shall strengthen your heart, all ye that hope in the LORD.
