If God was hidden from us and we could only discover little-by-little what He was like, then you might be right. But God isn't like that. H has already revealed Himself to us -- totally and completely.
Let me explain. Have you ever asked yourself how we can know anything at all about God? The answer is clear: We can only know about God if He has revealed something about Himself to us. And He has done this -- deliberately and openly. God hasn't hidden Himself from us; He wants us to know Him!
How has He done this? One way is through the universe He created. The world is God's handiwork; it didn't just happen -- He made it. And just as an artist reveals something of himself through his paintings, so God has revealed something of Himself through His creation. The Bible puts it this way: "Since the creation of the world God's invisible qualities -- his eternal power and divine nature -- have been clearly seen, being understood from what has been made" (Romans 1:20).
But God has revealed Himself finally and completely in a way that staggers our imagination: He became a man! That man was Jesus Christ, who was God in human form. Do you want to know what God is like? Look at Christ -- and when you do, you'll see not only that God is real, but He loves you and wants to come into your life to save you and give you His peace. Why not open your heart to Christ today?
