Cleanse me, O Lord, conform my heart to yours.

You desire truth in the heart;
   therefore in my secret heart teach me wisdom.
Wash me and I shall be clean;
   and I shall be whiter than snow.

~Psalm 51.6-7
  

Help me with self-control, Lord.

Let every man be quick to hear,
slow to speak, slow to anger;
for a man's anger does not fulfill God's justice.
 
If a man who does not control his tongue
imagines that he is devout,
he is self-deceived;
his worship is pointless.

~James 1:19-20, 26
