God directs His people to evaluate their resources by thoughtfully meditating on the blessings He has already given, so that offerings may be presented in proportion to those blessings rather than according to what one can safely afford. This evaluation requires honest reflection on what one has received, because human nature tends toward under-giving through fear, self-centeredness, or failure to consider God's gifts. Four common difficulties hinder such reflection: accepting blessings as mere natural occurrences, supposing one deserves them, mismanaging resources throughout the year, and passively forgetting their source. Forgetting proves especially serious, since it severs the connection between daily life and God's involvement, leaving no compelling reason to give back and resulting in insignificant offerings. God therefore commands His people to remember that He supplies the power to obtain wealth and that every blessing originates with Him. When Israel brought far more than enough for the tabernacle, the excess came from spoils God had first provided in Egypt, demonstrating that He blesses partly so His people may return an appropriate offering for His work. To bless God in return means to show Him favor, kindness, and respect by placing a monetary value on what He has given. Seven times each year this remembrance is required, so that appreciation for the priceless knowledge of His plan, forgiveness of sins, protection, healings, understanding of world events, guidance for marriage and child-rearing, and trials that produce growth may be expressed through sacrificial giving. Those who remember and respond in this way avoid the pattern of forgetting that led ancient Israel astray and instead make offerings that overflow, just as the Israelites did when building the tabernacle.
