Yes. God's ultimate plan is the restoration of all creation.
This cannot be accomplished if 90 percent (the narrow way theory) of all humanity is burning in the Lake of Fire with no hope of escape. Even believers with no works will escape through the flames. What does that tell you?
1 Corinthians 3:12-15
If anyone builds on this foundation using gold, silver, costly stones, wood, hay or straw, 13 their work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each person’s work. 14 If what has been built survives, the builder will receive a reward. 15 If it is burned up, the builder will suffer loss but yet will be saved—even though only as one escaping through the flames.
Christs words:
Matthew 20 28
''Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.''
Mark 10 45
''For even the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.''
So Christ doesn't say all will be ransomed and redeemed.
And the 1 Corinthians scripture is actually referring to heavenly rewards. Once a person is saved they are sealed til the day of redemption but they have work to do-soul winning:
1 Corinthians 3
11 For other foundation can no man lay than that is laid, which is Jesus Christ.
12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
13
Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
14 If any man's work abide which he hath built thereupon, he shall receive a reward.
15
If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
So saved Christians who do no work will still be saved but get no reward in heaven. The unsaved are damned.
Even if you do believe all will be saved in the end the questions still remain: Why the great commission? Why did Christ preach on Hell?
