Note 38 at Mt. 6:21: The reason for not laying up treasures on this earth is so that we will not have our hearts drawn away from the things of God (Mk. 4:19). A key to success in the kingdom of God is singleness of purpose (Prov. 23:7; Phil. 3:13; 4:8). We don't have the capacity to do our best in two areas at the same time (Mt. 6:24; Jas. 3:1-2); therefore, if we will simply put God and His kingdom first in every area of our lives, He will add unto us all the wealth that we need (Mt. 6:33). "The blessing of the Lord, it maketh rich, and he addeth no sorrow with it" (Prov. 10:22). It's when we covet after money that we "pierce ourselves through with many sorrows" (1 Tim. 6:10).
