It doesn't matter what opinions people have of God! It doesn't matter whether some say He is not real or there's no God. Some may even stop believing in Him or start doubting whether He's real because of whatever they may be going through....
But the fact is He is God! He doesn't have to force Himself onto people in order for them to believe in Him.
The Bible say, "The heavens declare the glory of God and the firmanent sheweth His handiwork." A quick scan and analysis of what surrounds us is sure evidence that truly He is God! It don't matter the theories man might concort to justify their own views about the creation but the Word of God remains true!
At the contest on Mt. Carmel, the Israelites i.e. the worshippers of Baal, finally opened their mouths and declared, "The Lord, He is God! The Lord, He is God!"
And I shout too that despite what I have encountered, THE LORD, HE IS GOD!
