Nehemiah 13:14 Remember me for this, O my God, and do not blot out my loyal deeds which I have performed for the house of my God and its services.
Three times in this chapter Nehemiah asks God to remember all that he is doing for God. He had just returned to the land and saw how the people had forgotten to follow God. He goes about righting the wrongs and for each one asks God to remember what he is doing. Later in the chapter he asks God to remember how people had defiled the priesthood, by sinning.
God does not forget. He knows all of what we have done, both the good and the bad. We will all be before the judgement seat and our deeds will be judged. For unbelievers, they will be judged to hell. For believers, we will be rewarded for the areas we were faithful.
Remember and do not forget, that God is all knowing and all of our lives are before Him. He knows all, there is no hiding anything from Him. Live your life appropriately.
