“And he is the propitiation for our sinnes: and not for ours onely, but also for the sinnes of the whole world.”
1611 King James Version (KJV)
2:2 And he is the propitiation - The atoning sacrifice by which the wrath of God is appeased. For our sins - Who believe. And not for ours only, but also for the sins of the whole world - Just as wide as sin extends, the propitiation extends also .
1Jo 2:2 And he is the propitiation for our sins. The mercy seat of the Tabernacle where God met man was called the propitiation. Christ is our mercy seat, where God meets us in mercy and forgiveness. And not for ours only. Christ's offering is for all. He tasted "death for every man" (Heb 2:9).
