According To His Purpose

Romans 8:28-30 (ESV Strong's)

28 And we know that for those who love God all things work together for good, for those who are called according to his purpose. 29 For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. 30 And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.

Our spirits come from God and are placed in these earthly bodies according to His purpose. He foreknew us all before we entered creation. He did so that we might be made in the image of His Son. This is accomplished by His Son laying down His life for us so that we would lay down our life for Him. He calls all of us to join Him in an everlasting life of love and light. 

Some do and some don’t. He chose us that we might choose Him. He does so for His glory and ours.
