A person can look at the marvels of creation and know there is a God who created it all. God reveals himself through nature, that is called general revelation. In the Bible in the book of Romans chapter 1 verse 18-21 were we read " For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, because what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse,".

To know about God or to know God and His attributes one must read the only place He has revealed Himself through special revelation, and that is in the Bible. Believers want to be around other believers. Who are believers? Those who obey His word. In John 3:36 we read, Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.

So if you are a believer, you are also an obeyer of the word. Hebrews 9:24-25 says "And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near."

In short, there is a God and He has revealed Himself in creation/nature, and in His Word-the Bible. He has commanded believers to meet together in church.

So then if you are a believer, find a Bible believing, Bible preaching and teaching church. Stay away from false churches as there are many, i.e. the Prosperity Gospel. Those are the ones who say "Name it and Claim it" etc.
