It's Elementary

"In [Christ] we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace that He lavished on us. With all wisdom and insight [God] has made known to us the mystery of His will, according to His good pleasure that He set forth in Christ, as a plan for the fullness of time, to gather up all things in Him, things in heaven and things on earth." (Ephesians 1:7-10 NRSV)

I'm a mystery buff, and I'm crazy about Sherlock Holmes books, movies, and trivia. I guess the attraction lies in trying to detect all the clues Holmes considered so obvious. As he would say to his sidekick, "It's elementary, my dear Watson." Because I love mysteries, I'm intrigued by the clues God has given us about the great mystery of His will. I've become a detective in the Word of God, where I find solutions to the mysteries of the universe.
[We can unlock] some of the mysteries found in God's Word: God's plan for redemption through Christ, His mysterious timetable for the gathering of His people into one, and His rich spiritual inheritance to all believers. These are significant discoveries for all Christians. But the greatest mystery to ponder is not what Christ has done but why. Why would Jesus pay for the penalty of my sin, with His precious blood? Because "Jesus loves me, this I know." It's elementary, my dear.
