and will settle disputes between strong nations far away.
They will hammer their swords into plowshares

2:14 For the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea
20:8-15 That evening he told the foreman to call the workers in and pay them, beginning with the last workers first. When those hired at five o'clock were paid, each received a full day's wage. When those hired first came to get their pay, they assumed they would receive more. But they, too, were paid a day's wage. When they received their pay, they protested to the owner, 'Those people worked only one hour, and yet you've paid them just as much as you paid us who worked all day in the scorching heat.'
"He answered one of them, 'Friend, I haven't been unfair! Didn't you agree to work all day for the usual wage? Take your money and go. I wanted to pay this last worker the same as you. Is it against the law for me to do what I want with my money? Should you be jealous because I am kind to others?'

6:39 And this is the will of God, that I should not lose even one of all those he has given me, but that I should raise them up at the last day. *John 13:3 Jesus knowing that the Father had given all things into his hands
6:45 No one can come to me unless the Father who sent me draws them, and I will raise them up at the last day. It is written in the Prophets: 'They will all be taught by God.' Everyone who has heard the Father and learned from him comes to me.
12:32 And when I am lifted up from the earth, I will draw (Greek, literal, DRAG) everyone to myself."
12:47 I will not judge those who hear me but don't obey me, for I have come to save the world and not to judge it.

11:32 For God has imprisoned everyone in disobedience so he could have mercy on everyone.
15:21 I have been following the plan spoken of in the Scriptures, where it says,
"Those who have never been told about him will see,
and those who have never heard of him will understand"
3:14,5 But if the work is burned up, the builder will suffer great loss. The builder will be saved, but like someone barely escaping through a wall of flames.
If anyone's work is burned up, he will suffer loss, though he himself will be saved, but only as through fire.

which He lavished on us. In all wisdom and insight
He made known to us the mystery of His will, according to His kind intention which He purposed in Him
with a view to an administration suitable to the fullness of the times, that is, the summing up of all things in Christ, things in the heavens and things on the earth. In Him
also we have obtained an inheritance, having been predestined according to His purpose who works all things after the counsel of His will,
4:13 This will continue until we all come to such unity in our faith and knowledge of God's Son that we will be mature in the Lord, measuring up to the full and complete standard of Christ.

in heaven and on earth and under the earth,

everything to himself.
He made peace with everything in heaven and on earth
by means of Christ's blood on the cross.
1:15 This is a trustworthy saying, and everyone should accept it: "Christ Jesus came into the world to save sinners"—

and I will never again remember their sins

3:18-20 because also Christ once for sin did suffer -- righteous for unrighteous -- that he might lead us to God, having been put to death indeed, in the flesh, and having been made alive in the spirit,
in which also to the spirits in prison having gone he did preach,
who sometime disbelieved, when once the long-suffering of God did wait, in days of Noah -- an ark being preparing -- in which few, that is, eight souls, were saved through water;
3:9 The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance. *(John 13:3)
2:2 He himself is the sacrifice that atones for our sins—and not only our sins but the sins of all the world.
3:5 And you know that Jesus came to take away our sins, and there is no sin in him.
4:10 This is love: not that we have loved God, but that he loved us and sent his Son to be the payment for our sins.

and glorify your name?
For you alone are holy.
All nations will come and worship before you,
for your righteous deeds have been revealed."
20:14 Then death and the grave were thrown into the lake of fire.
