God deserves to be praised and glorified simply because he is God. His attributes and awesomeness command our very admiration, respect and honor. By revealing himself to us and making himself known from the beginning, we have a choice to make. We can glorify Him as God, offering our praise and thankfulness to Him or we can choose to walk away in darkness.
Paul describes this dilemma from the very beginning. Man choose not to Glorify God and as a result their thinking became futile. Another way to put this was that their thinking was vain or frivolous. It had no practical effect or result. It lacked serious value, substance or responsibility. As they continued on thinking this way, hardness of heart resulted.
When ones heart is continually dim or harden, then darkness slowly overtakes it until it is consumed. This condition is a process. Although many claim to be wise in the way of science or of this world, not recognizing the glory of God as sovereign and creator is complete foolishness.
The trouble with choosing not to identify God as He is or being thankful of what He has done, is the condition it leaves our heart. Over time, as our hearts became toughened to the truth of God. It is much harder to receive the truth from God's word or the seeds of life that is able to save us unless we condition our hearts from the beginning to receive it.
Today, do not waste time in unthankfulness. Take a moment to praise the Lord for who he is. Praise Him for the world he created. Glorify Him for sending His son to redeem us. Give thanks to Him and bless His name continually. David said in Psalm 34, "his praise will always be on my lips" Make it your mission today to incessantly praise the Lord in everything you do!
