Jacob was initially described in the scriptures as a deceiver and manipulator, but in the process of serving Laban for twenty years for his two daughters and securing a flock of animals for himself, Jacob is taken through a process of sanctification to become the type of the true servant of God, Jesus Christ. The theme of sanctification helps us to see how we are positioned by God to take up the proper place to be of service to God and His church, and to all in the first Adam eventually (Act 26:13-18; 1Cor 12:4-7; 1Cor 6:2-3; 1Pe 2:9; Rev 20). This includes the process whereby the old man in us is being supplanted by the new man in Jesus Christ (Rom 5:10-21; 2Co 5:15-17; Col 1:13). This is the prayer and purpose of Jesus for His elect in this age (Rom 15:15-16; Eph 5:26-27; 2Ti 2:21):
Joh 17:15 I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil.
Joh 17:16 They are not of the world, even as I am not of the world.
Joh 17:17 Sanctify them through thy truth: thy word is truth.
