Since God is “a God of truth” (Deuteronomy 32:4), it makes sense that the words proceeding forth from His mouth would reflect and demonstrate the same nature as their author. According to the scriptures, this is exactly what has happened. The psalmist said, “thy law is the truth” (Psalm 119:142) “and all thy commandments are truth” (Psalm 119:151). The Lord Jesus confirmed this when He said, “Sanctify them through thy truth: thy word is truth” (John 17:17). If God is worthy of praise for being a God of truth, it only makes sense that His truth would also be worthy of man’s praise (Psalm 71:22). God, knowing this truth, magnified His word above all His name (Psalm 138:2).
Every person cannot give the same amount, but every person can give. According to our passage, “Every man shall give as he is able.” Because some people might use this as an excuse not to give, the Lord further states that giving should be “according to the blessing of the LORD thy God which he hath given thee.” The New Testament repeats this same principle in 1 Corinthians 16:2. Every man is to give “as God hath prospered him.” The book of Acts gives a practical example. In Acts 11:29, the disciples sent relief to their brethren and every man did so “according to his ability.” Each believer should give to the Lord corresponding to how the Lord has prospered him.
