Part 1 - God is a mystery
It has been said that to keep the romance alive in a relationship, one should always keep a little bit of mystery about themselves. Or that one should have a touch of unpredictability. The same could be said of God. God compares His relationship to us on one level to the relationship between a husband and wife. But where we can never have any mystery about ourselves to God, we can never truly say that we know all there is to know of God. He is always a mystery and is unpredictable to us. His ways are not our ways. His thoughts are not our thoughts. Isaiah 55:8-9 says, "For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts." We can never understand His ways, but that doesn't mean we shouldn't try.
The theologians Olson and Grenz said, "God is immanent within human experience as the transcendent mystery that cannot be comprehended in spite of its absolute nearness." In other words, not matter how close we get to God, He will always surprise and amaze us. If we are to keep 'the romance' of our relationship with God alive in our own hearts then we must keep the mystery of God alive. This does not mean that we don't try to understand Him. We should do all that we can to learn as much as we can about God and His ways. Psalm 25:4 reflects what should be the cry of every heart, "Show me Your ways, O LORD; teach me Your paths." We should always strive to learn more of Him, but to also keep a wonder and awe of Him in our hearts.
What I consider the most mysterious thing about God....the one thing that I will never understand completely, is how He can love me. He is the creator of all things. John chapter 1 says that "all things were made by Him; and without Him was not any thing made that was made." He created all that there is. In Isaiah, He says, "My hand also has laid the foundation of the earth, and my right hand has spanned the heavens: when I call to them, they stand up together." (Isaiah 48:13) He holds the universe in the palm of His hand. If He but chose to close His hand, we would cease to exist. And none could condemn Him for He would be just in doing so. BUT....I love that word....but "God so loved the world, that He gave His only Son, that whosoever believes on Him should not perish, but have eternal life." He loves me. What else can I say? I am loved by the One who created all that there is.
Think of this....the One who created the tree that was used to make the cross gave His life on the cross that I might be able to come to Him. Ah, the wonder of it all. What can I do? How can I repay? Nothing, no way. All I can do is love Him in return and worship Him with all that I am and all that I do. All I can do is hide His Word in my heart that I might not sin against Him. (Psalm 119:11) All I can ask is that words of my mouth and the thoughts of my heart are pleasing and acceptable unto Him.
I could go on forever on the wonder and mystery of God. But I hope I sparked an interest in learning more about Him. I pray that you will find the wonder and mystery of Him who gave His life for us.
