Ecclesiastes 1:3 – What profit hath a man of all his labour which he taketh under the sun?
Do you ever wonder why you exist? Why were you born, and why are we here? Generally speaking, our existence is rather in insignificant in the expanse of the universe. If you believe humanist apologists, our purpose is self derived and relative to our background, education, and will to excel. Or if you read the nihilists, we have no purpose, only experience. Both of these philosophies are ultimately self-centered with no greater order to which we all must submit.
Does this satisfy your yearning for purpose and meaning? Probably not. We may disagree on the details, but I believe all Christians would agree that our purpose lies with God. Like the vessels of the potter and the art of the painter, our lives are meant to glorify the Lord. The only way to do that is obedience. No child ever glorified their parents by willful rebellion, and no amount of earthly sacrifice or donations to charities can make up for sins.
“Will the Lord be pleased with thousands of rams, or with ten thousands of rivers of oil? shall I give my firstborn for my transgression, the fruit of my body for the sin of my soul? He hath shewed thee, O man, what is good; and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?” (Micah 6:7-8). “Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man” (Ecclesiastes 12:13). Our purpose then is repentance and faithful humble service as vessels of honor as a living sacrifices.
