“For man also knoweth not his time: as the fishes that are taken in an evil net, and as the birds that are caught in the snare; so are the sons of men snared in an evil time, when it falleth suddenly upon them.” Ecclesiastes 9:12
Sons of men have demonstrated a vast knowledge in many things, but the wise Solomon says; sons of men do not know their time.
Think of the many who have slipped into eternity suddenly and unexpectedly they were taken as a bird or as the fishes in the sea out of their natural habitat. Sons of men think they have all the freedom and time to pursue their goals, however, they know not their time.
Man is a sinner; Christ died for those whom the father would give to him, they are drawn through the preaching of the gospel.
On the other hand; sons of God are ever watchful for that great and notable day. We are all sons of men in Adam. Wonderfully those who have come to know the Lord Jesus Christ are made sons of God.
Do you have this assurance?
