Seventh-day Adventist Church
Perfection is a goal we should work towards. It's in the Bible, Matthew 5:48, TLB. "But you are to be perfect, even as your Father in heaven is perfect."
Perfection is a process of listening, learning, and growing with the help of Jesus. It's in the Bible, Colossians 1:28, TLB. "So everywhere we go we talk about Christ to all who will listen, warning them and teaching them as well as we know how. We want to be able to present each one to God, perfect because of what Christ has done for each of them."
Perfection will be completed in us when Jesus comes. It's in the Bible, Jude 24-25, TLB. "And now—all glory to Him who alone is God, who saves us through Jesus Christ our Lord; yes, splendor and majesty, all power and authority are His from the beginning; His they are and His they evermore shall be. And He is able to keep you from slipping and falling away, and to bring you, sinless and perfect, into His glorious presence with mighty shouts of everlasting joy."
