Ecclesiastes 12:13-14

Let us hear the conclusion of the whole matter: fear God and keep His commandments, for this is man’s all, for God will bring every work into judgment, including every secret thing, whether good or evil.  

The most beneficial thing we can do as Christians are to work at keeping God’s commandments.  We all will be judged for our works, good or evil, that we have done on this earth.  Nothing is hidden from God or done in secret.  We must develop our integrity and faithfulness to His word.  As we do this making the decisions to avoid sins becomes easy.
