ya think He broke the law, such that He needed mercy, redemption & salvation?
because the psalmist did:
let Your mercies come also to me
(Psalm 119:41)
my soul faints for Your salvation
(Psalm 119:81)
save me
(Psalm 119:94)
my soul faints for Your salvation
(Psalm 119:123)
deal with Your servant according to Your mercy
(Psalm 119:124)
redeem me
(Psalm 119:134)
save me
(Psalm 119:146)
redeem me
(Psalm 119:154)
there is much more than this but this is more than enough for the point.
seriously have you not even read it?
