The Process

Romans 8: 28-30

And we know that God causes all things to work together for good to those who love God, to those who are called according to His purposes. 

We can confidently trust God to be powerful enough to use even the worst, destructive and evil things to fit into His good plan to give us good, in this life and eternal life forever. But only for those who He has called. And it's all to fulfill the purposes for which He made us and called us.

For whom He foreknew, He also predestined to become conformed to the image of His Son,

God knew who would be in His own Family, and determined the destination we would arrive at when He finished changing us from the vile sinners we are into the pure, shining, Resurrected being we will be, like Jesus is now.

That He might be the firstborn among many brethren;

The term "firstborn" is a position in a family given to the preeminent sibling, even if not actually the first one born. Jesus was always the Son of the Father, and holds that preeminent position. He didn't have to be "born" to be the Son. And the Father wanted many, many more, so He makes us brothers and sisters to Jesus in becoming our Father by the New Birth. 

And whom He predestined, those He also called;

The ones God chose before He created the Universe are the ones He is calling to Himself to be His children.

And whom He called, these He also justified; 

Those who are called to Salvation are saved from the power of sin in their lives, and will be delivered from the very presence of sin, by cleansing by the sacrificial Blood shed on Calvary. That Blood completely washed away every stain of sin, justifying the recipient by putting his sin on Jesus and Jesus' righteousness on the penitent. 

And whom He justified, these He also glorified.

The final destination is our glorification, when we are resurrected as Jesus was, and our physical bodies will be changed into glorious spiritual bodies. Because God began this process in each of us, He will finish it. He always finishes what He starts, so our glorification is just as sure and real today as our physical life is right now. 

And we can know all this for sure, as we trust our Father in His truthfulness and faithfulness. This is our faith. 

Even so, come, Lord Jesus!
