Below are a few comments from Ellen White and the Bible about our condition when Jesus comes.
"The soul who sees Jesus by faith, repudiates his own righteousness. He sees himself as incomplete, his repentance insufficient, his strongest faith but feebleness, his most costly sacrifice as meager, and he sinks in humility at the foot of the cross. But a voice speaks to him from the oracles of God's Word. In amazement he hears the message, 'Ye are complete in Him.'" FW 107
"Beloved, now are we the sons of God, and it doth not yet appear what we shall be but we know that, when he shall appear, we shall be like him; for we shall see him as he is." 1 John 3:2
"Like Him. This points to the fulfillment of God's plan for fallen man -- restoration to the divine image...It is God's design to restore that similitude by giving man victory over sin and over every temptation. The restoration will be completed AT THE SECOND COMING." 7 BC 649
"Our earthly life, however long, honored, or useful it may be, is but childhood, frail, imperfect, and undeveloped. Manhood, with its full, perfect, glorious development, will come, when, freed from the taint of sin, we stand among the redeemed throng. Then we shall enjoy a life which measures with the life of God"
ST, June 9, 1881 par. 21
"Christ's character stands in place of your character, and you are accepted before God just as if you had not sinned." SC 62
"So I will be your representative in heaven. The Father beholds not your faulty character, but He sees you as clothed in My perfection. I am the medium through which Heaven's blessings shall come to you. And everyone who confesses Me by sharing My sacrifice for the lost shall be confessed as a sharer in the glory and joy of the redeemed." DA 357
"We are not to be anxious about what Christ and God think of us, but about what God thinks of Christ, our Substitute. Ye are accepted in the Beloved." 2SM 33
