Why has God saved us? So that we could have fellowship with Him? Yes. So that we would glorify Him here on earth? Of course. So that we would be a witness and ambassador for Him? Definitely. But He has us here on this planet for a very brief period of time for another purpose too. The first part of Romans 8:29 touches on it: “For those whom He foreknew, He also predestined to become conformed to the image of His Son…” Here it teaches that He chose and saved us so we would become like Jesus. This is what sanctification is all about, day by day gradually becoming less and less like the world, and more and more like the Savior. God is preparing us to spend eternity with Him, but know for sure that He will change us, right here and right now, if we will only let Him.
