Romans 1:21 "For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened."
Knowing God is only part of our goal in this life. Giving God glory is the original 3G network that He set up. He wants us to acknowledge Him, praise Him and give thanks to Him. Living life with these characteristics assures us that our minds will be sharp and our hearts will be pure. Failing to keep Him first leads to futility and darkness: separation from His plans and purposes.
Why not make sure that you are on the 3G network today...Give God Glory!
