What was it that attracted you to God?
For me it was His redemption, unconditional love and acceptance. He knew all my junk but still I felt His love and forgiveness the moment I surrendered my life to Him.
What keeps me in relationship with Him, is His never-ending love, grace and beauty. I feel His love each day, His grace when I make mistakes and He shows me His beauty more each day.
We should never stop falling in love with God, just as we should never stop falling in love with our spouse. Each day we need to see them both in a new light, a new appreciation.
God wants to reveal Himself to us more each day, we just have to let Him.
