Yet, no one has yet entered the Innermost, because no one yet has kept "the law of the spirit of life" (Romans 8:2):
What Colossians 2: 9-15 is to you, all of Romans 8 is to me, it has it all, even Universalism in vs 21:
ROMANS CHAPTER 8 KJV
Colossians 2:9-15 and Romans 8 explain and enhance one another, for sure.
Highlights of Romans 8 (for those interested - any translation will do):
KJV - "There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. 2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death."
NLT - "The law of Moses was unable to save us because of the weakness of our sinful nature. So God did what the law could not do. He sent his own Son in a body like the bodies we sinners have. And in that body God declared an end to sin's control over us by giving his Son as a sacrifice for our sins. He did this so that the just requirement of the law would be fully satisfied for us, who no longer follow our sinful nature but instead follow the Spirit."
NLT - "And Christ lives within you, so even though your body will die because of sin, the Spirit gives you life because you have been made right with God."
NLT - "For his Spirit joins with our spirit to affirm that we are God's children. And since we are his children, we are his heirs. In fact, together with Christ we are heirs of God's glory. But if we are to share his glory, we must also share his suffering."
NLT - "Against its will, all creation was subjected to God's curse. But with eager hope, the creation looks forward to the day when it will join God's children in glorious freedom from death and decay. For we know that all creation has been groaning as in the pains of childbirth right up to the present time."
NLT - "And we know that God causes everything to work together for the good of those who love God and are called according to his purpose for them. For God knew his people in advance, and he chose them to become like his Son, so that his Son would be the firstborn among many brothers and sisters. And having chosen them, he called them to come to him. And having called them, he gave them right standing with himself. And having given them right standing, he gave them his glory."
NLT - "Who dares accuse us whom God has chosen for his own? No one--for God himself has given us right standing with himself. Who then will condemn us? No one--for Christ Jesus died for us and was raised to life for us, and he is sitting in the place of honor at God's right hand, pleading for us."
