“For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.” (Romans 8:38-39)
The verb persuaded is in the Greek perfect tense, thus it is indicating a situation in which Paul has made a decision and the conclusions of that decision are unalterable. Paul is persuaded and nothing can change it! Departure from the body cannot separate the believer from God's sight. Life, with all of its trials, failures, and disappointments cannot separate the believer from God's sight. Supernatural beings, whether good or evil, cannot alter God's faithfulness to His redeemed. The dark powers and principalities of this world with whom the believer has his warfare (Ephesians 6:12) are no match for Christ's love. Neither the things that will be, nor the things that have been, including past sin, are any match for God's righteousness. Not even the height of heaven or the depth of hell could make God forget His promise of “...whosoever will, let him take the water of life freely (Revelation 22:17).” And if that were not enough, God adds nor any other creature. Sometimes it seems that the greatest enemy of all is the flesh. Yet, not even this creature is able to remove the believer from Christ's grasp.
No one is worthy of salvation. Every one is wicked and condemned before a holy God, yet by grace God has enabled His salvation to be accessed through faith, and to those who choose the way of God-fearing faith in Jesus Christ, He has given the promise of the Spirit, the Spirit of life, hope, adoption, and eternal security. He convicts, regenerates, permanently indwells, fills, and secures “...mh. kata. sa,rka peripatou/sin( avlla. kata. pneu/ma [the one who not according to flesh is walking, but according to spirit- literal translation] (Romans 8:1).”
