The gospel of Jesus Christ shows us that the earthly life of believers, while not complete as it will be in glory, is also not vain as Solomon thought.
All go to one place. All are from the dust, and to dust all return. Who knows whether the spirit of man goes upward and the spirit of the beast goes down into the earth? So I saw that there is nothing better than that a man should rejoice in his work, for that is his lot. Who can bring him to see what will be after him? Ecclesiastes 3:20-22
He who supplies seed to the sower and bread for food will supply and multiply your seed for sowing and increase the harvest of your righteousness. You will be enriched in every way to be generous in every way, which through us will produce thanksgiving to God. For the ministry of this service is not only supplying the needs of the saints but is also overflowing in many thanksgivings to God. Second Corinthians 9:10-12
Solomon (who, we believe, wrote the book of Ecclesiastes) invested the time, money, and effort to pursue the meaning of life. But he came up with a rather bleak picture. After all his study and experimentation, he concluded that “All is vanity.” The best humans can hope for, he wrote, is “To be joyful and to do good as long as they live; also that everyone should eat and drink and take pleasure in all his toil—this is God’s gift to man” (3:12-13). Somehow it feels like something is missing, something that transcends this world. Certainly, Solomon grasps this too, as he says, “[God] has put eternity into man’s heart, yet so that he cannot find out what God has done from the beginning to the end” (3:11).
But God’s self-revelation continued with the coming of the Messiah, the Lord Jesus Christ, and the announcement of the Kingdom of God. Paul writes to those in Corinth who have heard this message and who are trusting in God’s Son for salvation. He tells them that their faith expressed in generosity for the poor is actually sowing a harvest of righteousness that results in praise and thanksgiving to God.
Think about it
When God’s people use the resources He supplies to serve others, this action produces win-win results for all. Blessing flows to the generous and to the needy. God is glorified. Far from being a vain, useless enterprise, generosity and good works produces lasting fruit. Take opportunities to give today. May the eternal, triune God be glorified and may you be blessed! Life is not vain and neither are good works done for Him.
