Reproduction has been part of God’s plan from the beginning (Genesis 1:28; 9:1).
Jesus said to His disciples, “ ‘By this My Father is glorified, that you bear much fruit. … I chose you and appointed you that you should go and bear fruit, and that your fruit should remain.’ ” John 15:8, 16
Jesus speaks here of the spiritual reproduction of the divine character in other human beings. When I am connected with Christ, then His life will flow through me to those around me, and His character will then be reproduced in others. It is the privilege of every Christian to be a coworker with Jesus in this work. (See John 15.)
“Tell the people of Him who is ‘the Chiefest among ten thousand,’ and the One ‘altogether lovely.’ The Song of Solomon 5:10, 16. Words alone cannot tell it. Let it be reflected in the character and manifested in the life. Christ is sitting for His portrait in every disciple. Everyone God has predestinated to be ‘conformed to the image of His Son.’ Romans 8:29. In everyone, Christ’s long-suffering love, His holiness, meekness, mercy, and truth are to be manifested to the world. …
“The Saviour longs to manifest His grace and stamp His character on the whole world. It is His purchased possession, and He desires to make men free, and pure, and holy. Though Satan works to hinder this purpose, yet through the blood shed for the world there are triumphs to be achieved that will bring glory to God and the Lamb. Christ will not be satisfied till the victory is complete, and ‘He shall see of the travail of His soul, and shall be satisfied.’ Isaiah 53:11. All the nations of the earth shall hear the gospel of His grace. Not all will receive His grace; but ‘a seed shall serve Him; it shall be accounted to the Lord for a generation.’ Psalm 22:30.” The Desire of Ages, 826–828
“Christ is seeking to reproduce Himself in the hearts of men; and He does this through those who believe in Him. The object of the Christian life is fruit bearing—the reproduction of Christ’s character in the believer, that it may be reproduced in others.” Christ’s Object Lessons, 67
