It is easy for believers to presume the Word of God only applies to this lifetime. Yet, the Word of God is just as eternal as God. When Jesus told his disciples: "Deny yourself and take up your cross," and follow me to store up treasures in heaven, he was saying the same thing he will say to the resurrected in the Age to come.
Holy men and women of God become PARTAKERS OF THE DIVINE NATURE through attaining to the calling and progressing on by sacrifice and obedience into a mastery of walking in the Spirit where they store up treasures in heaven as God pleases according to their dedication to finding and doing his perfect will.
The Church does not enter into the fullness of the divine nature in their human vessels while serving two masters, although there are occasional spiritual experiences. There are too many distractions, too many entanglements, too little time, and too little willingness to crucify the flesh. The Church revels in experiencing the divine Presence externally in the services where two or more are gathered to worship in Spirit and in truth. But there is much more of the divine ocean of God to experience.
The totally set aside disciple is filled with the Spirit when Christ visits their temple of flesh while they are hungering and thirsting to be filled with his righteousness. When such visitations progress from an inward infilling to a manisfestation of treasures of the divine nature, the Lord stores those treasures up for his servants in heaven where thieves cannot break in nor rust or moths ruin them. Those are true riches.
Those treasurable supernatural experiences in Christ will become manifest again in the Age to come when those who live holy lives in this lifetime are immersed in the Spirit of the Lord during THE THOUSAND YEAR REIGN OF CHRIST.
When the churchman worships in their congregation, they can feel the Presence of the Lord. WHERE TWO OR MORE ARE GATHERED IN MY NAME, THERE I AM the Lord says. The Lord is a Spirit AND MUST BE WORSHIPED IN THE SPIRIT. The more Spirit you have built in your being, the more you will be able to worship in the Spirit.
Disciples on up are able to draw closer to God than the churchman, having more Spirit. But the principle remains the same irregardless of where you are spiritually. "DRAW NEAR* TO GOD AND HE WILL DRAW NEAR TO YOU."
In THE THOUSAND YEAR REIGN OF CHRIST and on into eternity, the principle will remain unchanged. God's Word is as eternal as God who is THE SAME YESTERDAY, TODAY AND FOREVER.
We will not enter into a discussion here of all those things necessary to become one with God. Many of those principles are covered elsewhere in the library of this website. But all of those many principles also will remain unchanged. The prophecies and the stories pertaining to this world will no longer be in use in THE THOUSAND YEAR REIGN, but the principles or precepts will all remain the same.
The Word says GOD IS LOVE, and this cannot change although the resurrected will be more conscious of the love of God in themselves and in others in the worldwide awakening that takes place throughout THE THOUSAND YEAR REIGN OF CHRIST.
Knowing GOD IS LOVE may not mean much to you until you realize you are a vessel for the love of God to dwell in, for you to speak words and do deeds worthy of your love for him. Those who do not love do not know God. "IF WE LOVE ONE ANOTHER, GOD DWELLS IN US AND HIS LOVE IS PERFECTED IN US." 1 John 4:12
Once you recognize GOD IS LOVE, he becomes like the immovable sun in your spiritual sky shining on into eternity and whether it be in this lifetime or the world to come, you will need to manifest the light of his love perfectly.
Advancing into another Age doesn't change the eternal principles of the Word of God.
