"You will guard him and keep him in perfect and constant peace
[both it's inclination and it's character]
is stayed on You,
because he commits himself to You,
leans on You and hopes confidently in You.
So trust in the Lord --
commit yourself to Him, lean on Him, hope confidently in Him --
for the Lord God is an everlasting rock --
the Rock of Ages."
Isaiah 26 : 3 - 4 Amplified Bible
