Numbers chapter 7 lists all the sacrifices that each tribe brought to give to God. It is really a difficult read because of the repetition. Each tribe brought the same number of animals and one cannot help but ask why is the list of sacrifices repeated after the name of each tribe.
God wants us to know that nothing escapes Him. He takes personal inventory of every detail of lives. He keeps records of both the good and the bad. But there is a difference in how he handles our sins and our good deeds. We can never hide our sins from God. He sees all the ugly detail of all our thoughts and wishes. He records it all. They are all written down in his book. But, through our faith in Christ he promises to answer David’s prayer in Psalm 51: “God, be merciful to me because you are loving. Because you are always ready to be merciful, wipe out all my wrongs. Wash away all my guilt and make me clean again.” God erases the entries and says “I will remember them no more.” But with our good deeds and sacrifices we make for him, he only promises to remember them. “God is not unjust to forget our work and labor of love which we show toward his name.” (Hebrews 6:10) He forgets the bad but not the good.
