Read Ecclesiastes 12
Focus on verse 11-13
Every good presentation has a conclusion. In Ecclesiastes the Preacher (presumably Solomon) summarizes all that he as experienced and learned as he has observed the vanity of the humanity around him as well as the that which lies within him, and concludes that when it is all said an done it comes down to this; True wisdom comes from One source only. That source is the One Shepherd. (v. 11) He goes on to warn his son to beware of anything beyond these. (v. 12) In the final analysis, he narrows it down to one sentence. “Fear God and keep his commandments, for this is the whole duty of man.” (v. 13)
In other words, it would seem that his conclusion is that life apart from God is meaningless, and in my experience I would have to concur. One of the most common testimonies I have heard from people who have found their way back into relationship with God is some variation of “I tried all kinds of things to make my life mean something but nothing seemed to have any lasting effect, it was all meaningless – until I met Jesus Christ. When I surrendered my life to Him it changed everything, and I found the purpose and meaning that I was looking for.”
Too many people go through their entire lives without ever finding the purpose for which they were born. They stumble through life going from empty well to empty well in search of water and ultimately die of thirst unless they find the water of Life that only Christ can offer. That is the theme that is replayed in some way, over and over, not just in Ecclesiastes, but throughout nearly every book of the Bible. God revealing Himself to us through Jesus Christ, because He loves us and desires to win our hearts and minds to himself and set us free from the bondage and destruction of the enemy of our souls. All we have to do is respond.
