Psalm 139

"O Lord, you have examined my heart
and know everything about me." v.1

"Search me, O God, and know my heart;
test me and know my anxious thoughts.
Point out anything in me that offends you,
and lead me along the path of everlasting life." v.23-24
Sometimes we don't let people get to know us completely because we are afraid they will discover something about us they won't like. But God already knows everything about us, even the number of hairs on our heads and he still accepts and loves us. God is with us through every situation, in every trial - protecting, loving, guiding. He knows and loves us completely.

David ask God to search for sin and point it out, even to the level of testing his thoughts. This is exploratory surgery for sin. How are we to recognize sin unless God points it out? Then, when God shows us, we can repent and be forgiven. Make this verse your prayer. If you ask God to search yor heart and your thoughts and to reveal your sin, you will be continuing on "the path to everlasting life".
