Reconcilation is the same greek word as atonement. Christ thru the cross and his blood sacrifice has abolished the animosity and alienation between us and God.
Leviticus 8:14 And he brought the bullock for the sin offering: and Aaron and his sons laid their hands upon the head of the bullock for the sin offering.
8:15 And he slew it; and Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured the blood at the bottom of the altar, and sanctified it, to make reconciliation upon it.
These offerings pictured the atonement that Christ accomplished.
2 Corinthians 5:18 And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
5:19 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.
5:20 Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God.
5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
Christ takes our place and pays the penalty for our sin and gives us His righteousness.
The plea is to be reconciled to God thru faith in Christ Jesus.
