How can Christians have confidence at Christ's return?

In 1 John 2:28, John instructs believers to abide in Christ, assuring them that if they do, they will have confidence at His coming. When Christ returns, those who have abided in His grace will not be ashamed, as they will be clothed in His righteousness. This assurance is grounded in the belief that fellowship with Christ and obedience to His Word secures them a place in glory—free from guilt and shame. The focus is on a relationship characterized by trust and dependency on Christ, which ultimately leads believers to an eternal state of glory and acceptance before God.
