Hebrews 9:23-28 reveals Jesus' three distinct appearances across time that complete our salvation story. In the past, Jesus appeared on earth to remove sin through His one-time sacrifice. In the present, He appears in heaven as our advocate and intercessor before God. In the future, He will appear in the sky to bring final salvation to believers. These appearances show that salvation spans all of time—Jesus dealt with our sin problem, currently represents us before God, and will return to complete our salvation. This progression should transform how we live today with forgiveness, confidence, and expectancy.
