Sin is disobedience to and not matching God and his standard. Sin entered the human race through Adam and Eve and has separated God and mankind. All people have sinned and come short of God’s holiness and righteousness (Genesis 3.1-7; Romans 3.23, 5.12, 6.23; Ephesians 2.1).
Reconciliation is the Bible word that summarizes what God did—he made peace between God and man by removing the sin barrier. God is the one who works; he is the subject in reconciliation. Man is the benefactor, the object of reconciliation (Romans 5.10-11; 2 Corinthians 5.18-19; Ephesians 2.16; Colossians 1.20-22).
Righteousness—God is perfectly righteous to forgive sinners, credit righteousness to them, and grant everlasting life to all who believe in his Son because Jesus Christ took God’s judgment for mankind’s sin and satisfied God’s righteousness (Romans 1.16-17; 3.21-26).
For us teaches substitution—the way God provided reconciliation and our eternal salvation. God’s son, Jesus Christ, substituted himself for us and took God’s righteous judgment in our place instead of us (John 1.29; Romans 5.6, 8; 8:32; 1 Corinthians 15.3-4; 2 Corinthians 5.14-15, 21; Ephesians 5.2; Titus 2.14; 1 Peter 2.24).
God’s love is the motivation for the removal of the sin barrier (John 3.16; 1 John 4.10).
The mediator is the qualified person who removed the sin barrier between God and man. Jesus Christ is the one mediator. A mediator must have something in common with both parties. Christ is eternal God; he became man so that he might die for sinful man (1 Timothy 2.5; Philippians 2.5-11;).
Redemption—Jesus Christ, by his death in our place, paid the just price to free sinful mankind from the slave market of sin (Romans 3.24; Ephesians 1.7; 1 Peter 1.18-19).
The whole world, Unlimited atonement—Jesus Christ died for all the sins of all people (1 Timothy 4.10; 1 John 2.2).
Propitiation—The work of Jesus Christ on the cross satisfied all of God’s righteous and just demands (Romans 3.25; 1 John 2.2).
Regeneration—God gives spiritual life to each person who believes in Jesus Christ as savior (John 3.5-8; Titus 3.5).
Imputation—God credits or puts righteousness on the account of each person who believes in Jesus Christ as saviour (Romans 4.22-24; Philippians 3.9).
Justification—God looks at each believer in Jesus Christ and sees Christ’s righteousness on his account and therefore declares him righteous (Romans 3.24, 26, 28; 5.1; Titus 3.4-7).
Forgiveness—God frees the believer from the charges of sin that were against him (Ephesians 1.7; Colossians 2.13).
Grace describes the way God applied the work of Christ. Grace is the expression of the character of God on behalf of man. Grace means that God freely benefited man; God did the work and man benefits (Romans 6.23; 4.3-6; Ephesians 2.8-9; Titus 3.4-7).
Faith is dependence, trust, reliance on someone; it is accepting what God said is true. Jesus Christ is the only worthy object of faith for eternal salvation. Faith is the means by which each person benefits from God’s work and gains eternal life, or what we might call the experience of personal reconciliation with God (John 3.16; Romans 4.1-6; Ephesians 2.8-9; 1 John 5.13).
Position in Christ—When a person believes in Christ the Holy Spirit puts the believer in relationship with Christ, identifies him with Christ’s body the church, and the Holy Spirit indwells him (2 Corinthians 5.17; 1 Corinthians 12.13
