John calls us to marvel at the Father's astonishing love, that sinners are not only forgiven but adopted as His children. Those who abide in Christ can look forward to His return with confidence, not fear or shame. Though we do not yet see all our future glory, we know that when Christ appears we shall be like Him, for we shall see Him as He is. This hope is not just comforting but purifying, moving every true child of God to pursue holiness as we wait to see the Lord face to face.
