SHW:
Redemption is not completely explained in the Scriptures. It was taught through oral teaching.
Redemption most certainly is explained in the Scriptures, especially if you approach it from the Greek. It means to deliver by paying a price. Scriptures presents all of Adam’s race as slaves sold into sin (Rom. 7:14) and under the sentence of death (Rom. 6:23), but subject to redemption by the purchase price of the Redeemer. This redemption is described in three Greek words

1)
agorazo Meaning to purchase out of the market place (1 Cor. 6:20; 7:23; Rev. 5:9)
(2)
exagorazo Meaning to buy out of the market and remove from further sale (Gal. 3:13; 4:5)
(3)
lutroo Meaning to loose and set free (Titus 2:14; 1 Pet. 1:18); with its noun form
lutrosis (Heb. 9:12); and its intensive form,
apolutrosis which is commonly used to indicate complete release of a slave (Rom. 3:23; 8:23; 1 Cor. 1:30; Eph. 1:7,14; 4:30; Col. 1:14; Heb. 9:15; 11:35)Scripture clearly describes the believer’s redemption through faith in Christ as having been (
1)
purchased by the blood of Christ out of the slave market of sin, (
2) never to return and (
3) completely set free. Just as Jesus said: “
So if the Son makes you free, you will be free indeed” (Jn. 8:36). And Paul proclaimed to the church in Galatia where some desired to be enslaved under the principle of law: “
It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery” (Gal. 5:1).
Contrary to your assertion, one can see above that redemption is clearly explained in Scripture. What was taught by the Apostles on redemption, orally, was subsequently preserved for us in
Holy Writ. There’s no difference between what was orally taught and what was preserved in writing. It’s farcical indeed to think they’d be different.
All men are redeemed, yet not all are saved.
All men are not redeemed. It’s true that Christ accomplished the work of redemption on the cross for all men, and that He stated concerning that work: “
It is finished.” But one does not enter it, nor is His finished work of redemption appropriated to anyone, until they BELIEVE in Him. At the time of personal belief in Christ His work of redemption is Divinely applied to the believer in full (
agorazo, exagorazo, lutroo). Redemption is part of Divine salvation through faith in Christ alone. The saved are completely redeemed and the redeemed are completely saved. It’s impossible for the redeemed not to be saved or vice versa. The
redeemed and the
saved are one and the same people.
The redeemed and unsaved have not done their part." —John Martignoni
JM grossly errs by teaching universal redemption (which is different from “
unlimited redemption”) and salvation by works. Both are contrary to Scripture.
Salvation: Those who do their part in imitating Christ’s life (those who abide in Christ) are saved. Those who do not do their part are not saved.
Translated: Salvation by works.Eph 2:8 “For
by grace you have been saved
through faith; and that not of yourselves,
the gift of God;
not as a result of works, so that no one may boast.”
We remain in the state of grace by obeying God’s commandments and thereby loving God and neighbor which I have documented by Scripture in previous posts.
Confirming your “gospel” of salvation by law keeping.
If we sin deliberately after we are saved, then Jesus’ sacrifice no longer saves us. (Hebrews 10:26-39)
Confirming your rendering of the cross to be insignificant.
Since you claim to believe and understand Scripture, then why do you not obey 2 Thessalonians 2:15? “So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.”
Paul is saying they’re the same, not different. Whether by word of mouth or by letter the traditions (teachings) remain the same. We’re handed down to us in the twenty-first century, through the
theopneustos (God-breathed) Scriptures, the same gospel and the same Apostolic teachings that were orally presented to the churches of the first century. It’s the way God has preserved His Word on earth since Moses.
We are justified by our works as proof of our faith.
You err.Rom 4:5 "But to the one
who does not work, but
believes in Him who justifies the
ungodly,
his faith is credited as righteousness,What’s credited as righteousness, SHW? His works? His “
proof” of faith by a lifetime demonstration of works? His godliness? No, No, No. What does God say in His preserved, written Word? “
…his FAITH is credited as righteousness.” You operate under the false assumption that God is finite and cannot recognize faith and therefore one must provide Him proof throughout his life before He can finally justify him. You err both in your “gospel” of salvation by works and your concept of God. The latter is the cause of the former.
SHW, your “guardian angel” isn’t doing well for you. Are you allowed to trade him in for another?
