We have eternal spiritual life now, from the moment we are born again, and because we have ETERNAL life now through the Spirit of Christ in us, we are now waiting for and anticipating immortal/incorruptible physical life that shall be at His coming when the last trumpet sounds. It is at Christ's coming again that believers shall either be resurrected from the grave our body changed from mortal to immortal, or if we are still physically alive at His coming again, we shall be changed from mortal body to immortal and incorruptible body and together we shall all meet the Lord in the air.
Then at the GWTJ we who are eternally alive through immortal/incorruptible body will be at the right hand of God, not to be judged but to inherit the everlasting Kingdom of God prepared for us on the new earth to live with Christ forever.
Yes, we are spiritually alive possessing eternal life from the moment we have been born again. You say I continue to bring up the doctrine of eternal security through Christ, but it is you who keeps saying the eternal life we have in Christ is NOT really eternal until our body is changed from mortal to immortal and corruptible to incorruptible. Have you not read that life is of the spirit and the flesh profits nothing? You want to make eternal life dependent upon the flesh, and our obedience while clothed in mortal, corruptible body destined to die. How are believers faithful unto death? Have you not read that the obedience we display in this mortal flesh, is done by the power of God working in us? What have we that has not been granted us through the Word by grace of God working in us?
John 6:63 (KJV) It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
1 Thessalonians 2:13 (KJV) For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
Philippians 2:12-13 (KJV) Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. For it is God which worketh in you both to will and to do of his good pleasure.
John 3:27 (KJV) John answered and said, A man can receive nothing, except it be given him from heaven.
2 Corinthians 3:5 (KJV) Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;
You quote these verses thinking to change statements of FACT to conditional statements that are dependent upon our faithfulness while clothed in mortal bodies of death.
The man who does not endure temptation does not love the Lord; the words are spoken to them that love Him. James is not saying what you imagine, that the crown of life is dependent upon a believer's good works in the flesh until the day they physically die. Because James also says that man is tempted when he is drawn away of his own lust and enticed by his fleshly desires which shall bring forth death to them who know NOT the Lord.
James 1:13-16 (KJV) Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: But every man is tempted, when he is drawn away of his own lust, and enticed. Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death. Do not err, my beloved brethren.
The statement of FACT stands "be thou faithful unto death, and I will give thee a crown of life." Life that shall be of immortal/incorruptible body made alive through our eternal spirit that shall come with Christ.
Trying to make John's statement of FACT conditioned upon our faithfulness unto death doesn't work for you either. Because John is writing these words to those who are overcomers and shall not be hurt of the second death. That is those who already possess everlasting eternal spiritual life through the Spirit of Christ in us. We have already partaken of the tree of life, and the second death NOW cannot hurt us.
Revelation 2:7 (KJV) He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.
Revelation 2:10-11 (KJV) Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life. He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death.
1 John 5:4-5 (KJV) For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
Revelation 21:7 (KJV) He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
