In the same vein:
Proof would negate love:
If God bowled us over with evidence, it would negate love.
Imagine if God reveals Himself to the point that everyone “has to” believe in Him (if it would be possible). The problem with such a scenario is that there would be no love relationship with Him, it would be forced relationship.
The philosopher Soren Kierkegaard imagined a king who loved a humble maiden. He had all the power to force her to come to his palace, marry him and be crowned the queen. But that would not mean that she loved him. It would probably mean the opposite.
The king could easily overwhelm a cringing maiden. But that is not what he wanted. He wanted her love.
In a similar way, God wants our love. He has certainly displayed His power through creation and given plenty of evidence for belief, (see my points below). But most of all He wants us to love Him.
He wants us to say with the Apostle John “We love him, because he first loved us.” (1 John 4:19 KJV)
God reveals Himself to us, He just doesn’t do a very good job of it. That’s what many seem to think. In fact, I’ve sometimes thought that myself. I’ve wondered things like: Why doesn’t God make it more clear that He exists and His plan for humanity? Why be mysterious? Why not make things obvious? Why make people take a step of faith to believe?
