We all, with unveiled faces, are looking as in a mirror at the glory of the Lord and are being transformed into the same image from glory to glory; this is from the Lord who is the Spirit. —2 Corinthians 3:18, CSB
A simple truth: Jesus changes people. And when a believer comes to Jesus, he begins a journey in becoming more and more like Jesus, being slowly sanctified through the Spirit. Of course, this journey is not easy or fast, because it is a daily process. And it’s not a matter of self help or self improvement, because this is a supernatural work in the believer. Even more, the goal is to be less and less like the former self and more and more like Jesus Christ, so that the believer does not merely look like a better reflection of himself in the mirror, but instead something much, much better and permanent: the believer becomes a God-shaped reflection of Christ.
The point is this: stop trying to do it alone. You can’t do it without the Spirit’s work within your soul. This means that instead of trying to be a better version of yourself, focus on the One who is perfect already. In other words, instead of trying to make the imperfect, perfect, let the Perfect One, the Sinless One, the Savior, God-man, Jesus, do His work in you.
Is that impossible? Yep. In natural terms, it is. But with God, all things are possible, and when we mess up and blow it and sin and sin again, we can have confidence to ask for forgiveness and press forward after that. God is like that, both disciplining and forgiving those He loves and pressing them to conforming to His image more and more. He is in the restoration business, a business we all need every day.
So let the Spirit speak and work in you. Be changed in Christ. Come to Jesus for your salvation and forgiveness for your sins. Grow by reading His Word, by worshipping with other believers, by praying to the One who created all things. And look forward to the future in Christ, the day when we will all see Him as He is, the day when the mirror is no longer cloudy and the full knowledge is no longer veiled.
May your journey go well and your focus remain on your Savior, Jesus.
