Eph 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
Eph 1:14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
Like you, I firmly believe in once saved-always saved, based on your Scripture references and mine.
I likewise fully agree!
Colossians 3:1-4 KJV
1) If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God.
2) Set your affection on things above, not on things on the earth.
3) For ye are dead, and your life is hid with Christ in God.
4) When Christ, who is our life, shall appear, then shall ye also appear with him in glory.
If you've been raised with Him, this means you've died with Him, and that you will appear with Him in Glory.
1 John 3:1-3 KJV
1) Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.
2) Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
3) And every man that hath this hope in him purifieth himself, even as he is pure.
If we are His children now, when we see Jesus, we will be like Jesus.
Philippians 3:20-21 KJV
20) For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:
21) Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
If you are a citizen of heaven, Jesus will change "the body of our humiliation" to be like His glorious body.
Ephesians 4:30 KJV
And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
The Holy Spirit is God's seal of ownership of us, preserving His claim upon us until the day He claims His possession.
1 Peter 1:3-5 KJV
3) Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
4) To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
5) Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
God is Who keeps us by His power, having assured us an incorruptible inheritance, reserved for us, this based on Jesus' resurrection from the dead, an accomplished fact, outside of ourselves.
Romans 5:18 KJV
Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
Romans 5:18 LITV
So then, as through one deviation it was toward all men to condemnation, so also
through one righteous act toward all men to justification of life.
Romans 5:18 EMTV
Therefore, as through one man's offense judgment came to all men, resulting in condemnation, even so
through one Man's righteous act the free gift came to all men, resulting in justification of life.
2 Corinthians 5:18-19 KJV
18) And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
19) To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
God reconciled the world to Himself quite apart from us. We receive a reconciliation obtained on our behalf by Jesus, through His death, "one man's righteous act", and His resurrection.
This was accomplished having nothing to do with how good or bad anyone is, God did this for the world through Jesus, and we simply receive or we don't.
Romans 5:10-11 LITV
10) For if while being enemies we were reconciled to God through the death of His Son, much more, being reconciled, we shall be saved by His life;
11) and not only so, but also glorying in God
through our Lord Jesus Christ, through whom we now received the reconciliation.
God reconciled sinners to Himself, not because they were righteous, they were unrighteous. All of us! We've received a free gift reconciliation to God, and having received the reconciliation, having received Jesus, are are born into His family.
If we were reconciled to God even being His enemy, even before receiving that reconciliation, and now, having received, we are His very children, how much better relationship do we have with our Creator? Infinitely better, it's through Jesus Christ, the Son of God Himself!
Much love!
