The good news in all of this is that God is the perfect Father. And He knows how to get the best out of all His children.
In the process of that completion - as His good work continues - there are going to be fiery trials. God is going to perfect us. He is going to try us and test us. At times we may not feel very important and we may want to let down.
But remember that God the Father has called us personally. And He wants to see us earn the highest, the most meaningful, the most useful, and the most helpful office that He can give us. He is working out a great purpose in our lives. It is far greater than we can begin to understand.
So let us work diligently in our efforts to imitate God. Never let down! Never let anything lead us to neglect or become complacent toward God! And never carelessly take Him for granted!
Always place Jesus Christ at the forefront of our minds. Always focus on the tremendous example He set. And always do everything we can to be like Him! Never take your eyes off God or the great purpose He has set before us.
Now if God predestines someone to be conformed to the image of His Son, has God ever failed at anything? Never! It says in Philippians 1:6 that God is able to finish what He starts. We stumble around. But God desires to save us. God desires that we be in His Kingdom and He has arranged for us to be resurrected at the time of the seventh trump, at the time of the return of Jesus Christ. He is preparing us to be conformed in the image of His Son so that we can rule under and with Jesus Christ in the Kingdom of God. Do you have that hope? Does it stir you that God has not failed at anything yet, and that it is His desire for you to be conformed to the image of His Son?
I am not saying that this will be easy because in order to do this He may have to give us some awfully great pain in order to bring it about. A great deal depends on whether or not we submit to Him; whether we do it willingly or whether we fight Him all along the way.
The promises that God gives us can give us peace of mind:
That is a promise from God. He called you. If you stay close to God, do your part, He will complete the promise and the work in you.
