God, who hath reconciled us to himself by Jesus Christ !
2 Cor 5:18
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;
According to this scripture, how did God reconcile [believers] to Himself ? Was it by their faith or repentance ? Was it by their obedience ? Does it say it was by their own freewill ? No, it was none of that which they did, no act of theirs, but He did it by Jesus Christ, meaning by His Death on the Cross 1 Pet 2:24-25
24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
25 For ye were as sheep going astray; but are now returned or reconciled unto the Shepherd and Bishop of your souls.
His death, and all it effected, set in motion reconciled those He died for back to God, the word reconciled in 2 Cor 5:18 is the greek word katallasoo , which means : I change, exchange, reconcile, change as when Two parties reconcile together, like marriage partners who had been estranged and at odds 1 Cor 7:11
11 But and if she depart, let her remain unmarried or be reconciled to her husband: and let not the husband put away his wife.
The word also denotes a change from enmity to friendship ! Not Gods enmity towards them, but their enmity towards God. By nature those whom Christ died for and reconciled to God were themselves enemies in their minds towards God, for so says the scriptures Rom 5:10
10 For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
Rom 8:7
7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
All men by nature are with a carnal mind, that's natural for men 1 Cor 3:3
For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
Col 1:21
21 And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he[Jesus Christ] reconciled
Now understand, this enmity we have by nature against God is overcome by the effects of Christ's death, causing us to come into a friendship/ fellowship in our hearts and affections towards God and the things of God, and of course our Faith to come to Him in a pleasing manner Heb 11:6 arises out what Jesus Christ by His work of the Cross effected ! Thats what Paul taught in 2 Cor 5:18 and Col 1:21 !
Now in 2 Cor 5:18 who are the Us ? 2 Cor 5:18
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;
Its all them He reconciled to God while they were being enemies Rom 5:10
10 For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
The Us of 2 Cor 5:18 is consistent with the we of Rom 5:10, in fact that word reconciled is the same in both places !
And folks ultimately thats who Christ died for, those who by Him come to Faith/ Friendship and Fellowship experimentally with God Triune !
BTW, that's who the world is in 2 Cor 5:19, a world of men and women of all nations, whose natural enmity against God has been overcome, and they be experimentally brought into the Fellowship/Friendship with God again through Jesus Christ, to whom be all the Glory ! 10
