Romans 8:29(KJV) For whom he did foreknow,
he also did predestinate to be conformed to the image of his Son,
that he might be the firstborn among many brethren.
There is something more. Far beyond having heaven as our home. We have been made partakers of a "divine nature" (2 Peter 1:4) so that as we make our decisions for the Lord something miraculous happens and we begin in some measure (30, 60, 100 fold) to reflect the character of Our Lord......until Christ be formed in you (Gal 4:19). Its not a life changed but a life exchanged. From "Glory to Glory", "Strength to Strength" and from "Faith to Faith". Its the "high calling" in Christ. A high plain of spiritual integrity...." ...its no longer I that live but Christ that lives in me..." (Gal 2:20) Only The Cross makes this possible...When Christ died we died (Rom 6:8)...only the life of the Son can please the Father....heaven will not be a place of mixture only measure.
Hebrews 2:10 (KJV)
For it was fitting for Him, for whom are all things and by whom are all things, in bringing many sons to glory, to make the captain of their salvation perfect through sufferings.
