A key element in my sermon today is the teaching that Christ has redeemed all people (universal atonement). Here’s an excellent summary of this teaching.
When Paul writes that Christ also loved the church and gave Himself for her” (Ephesians 5:25), he does not limit the redemption to the church, the believers, or the elect. Although it is true that these are the only ones who actually receive the benefit of Christ’s redemption, the Bible explicitly states that Christ redeemed all people. He is the Lamb of God who takes away the sins of the world (John 1:29). He is the propitiation for the sins of the whole world (1 John 2:2; 1 Timothy 2:6). He reconciled the world to God (2 Corinthians 5:19). “All people” even includes those who are ultimately lost in hell. They were bought by Christ too (2 Peter 2:1). There is no human being that was overlooked; Christ tasted death for every person (Hebrews 2:9). Although there is no redemption for the fallen angels, there is a perfect redemption for all people, including the worst of them. The apostle Paul declares: “This is a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief” (1 Timothy 1:15). All nations and races may gather under the cross of Christ and find redemption there.
