John's burden for believers is that they abide in Christ throughout their lives so that they have assurance of eternal salvation and no reason to be ashamed when Jesus returns (1John 2:28). John teaches that those who abide in Christ practice righteousness. The reason they do so, is because abiding branches know God's love for them in Christ, have been transformed by God's Spirit through new birth, and are setting their hope on the glory coming to them when Jesus returns. By focusing in faith on God's past saving grace through Christ's saving work, the Spirit's ongoing work, and the grace coming to believers when Jesus returns, one will abide in Christ and enjoy assurance of eternal life with God!
