The fruits of your labor begins with the Lord. The source of everything you gain or receive under the sun is acquired from God. Therefore, it is meaningless to labor without God as your source.
There is nothing better for a man, than that he should eat and drink, and that he should make his soul enjoy good in his labour. This also I saw, that it was from the hand of God. Ecclesiastes 2:24 KJV
For God giveth to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth travail, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit. Ecclesiastes 2:26 KJV
