Psalm 41:4:

I said, LORD, be merciful unto me: heal my soul; for I have sinned against thee.

Notes on Psalm 41:4:

You probably know from experience that if you sin, it has negative effects on your emotions.  Sin is never a blessing to you!  It can look like one on the surface but it will always cost you something.  This verse is a cry for mercy for soulish healing from woundedness that was related to sin.  We’ve all sinned, but our redemption includes soulish healing from woundedness that has resulted from OUR sins.  As in Psalm 107:17-20, God shows that He is so good that He will heal you of problems that you brought on yourself because of your sin!
