Romans 8:29 “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.”
We are to be “conformed to the image of the Son”. This forming of His life must take place during our “lifetime”. It is “here” under intense pressure, trials, tests and temptations that this is accomplished. In eternity there won’t be a devil to tempt us or a circumstance to test us. That “only” takes place here in this “Garden of Choice”. We must “overcome” the world as “The Firstborn” did. He is the pattern. (1 John 5:4-5) That’s how we will be measured when we stand before the Throne of God. The most important time in all eternity is “Right Now”. When we step out of time that “finished work” will be released into eternity. Death merely releases us from this body. It doesn’t change what we have become “spiritually” during our lifetime. Eternity will be a place of “measure” not of “mixture”. Only those who have unconditionally submitted their lives to His Lordship and successfully functioned under divine authority will be given the “eternal reward” of being “seated with Him”.
Revelation 3:21 “To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.”
