If you ever had any hope of trying to please God with your good, moral behavior, put that notion to rest. Psalm 14:2-3 should lay you flat.

2The Lord looks down from heaven on the children of man,
to see if there are any who understand,a
who seek after God.

3They have all turned aside; together they have become corrupt;
there is none who does good,
not even one.

How then will you be able to stand in the last day, when God judges the thoughts and intentions of the hearts of all, when all must give an account? Especially in light of the passage above, that there are none righteous?
