One of the great truths revealed in Scripture is that the end is determined from the beginning. What I mean by that is God sees the end from the beginning. He already has a plan for you. He has already got the whole thing worked out.
Consider what God told Jeremiah in Jeremiah 1:5,
"Before I formed you in the womb I knew you; before you were born I sanctified you; I ordained you a prophet to the nations."
Before Jeremiah was ever born, God had his destiny, a plan for his life, all worked out. That truth applies to you and me, and that helps me rest at night. It is great to know I do not have to figure this whole thing out. Sometimes we see through a glass darkly. But you know what? God sees everything perfectly.
This same truth is echoed in Ephesians 1:4,
Just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love.
Did you know you were chosen before God laid the foundation for this world? That was a long time ago. God knew you before you ever existed. He knew you before the world was here. You were chosen in Him. You were not an accident. God knew you.
Again, this truth is affirmed in Ephesians 2:10,
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
The beforehand is before the foundation of the world. Just like God knew you, He prepared specific good works for you that you should walk in them long before you ever came into existence.
He has your life mapped out. What a great comfort!
