The third characteristic of the truly elect and, therefore, of those who should have assurance of their eternal salvation is sanctification.
If you then perceive within yourself a hatred, repulsion, and sorrow concerning both the secret sins of your heart, as well as your sinful deeds, and if you find an inner delight and love for a godly spiritual frame and the practice of all virtues in the fear, love, and the obedience of God, as being His will; if you perceive within yourself the warfare between flesh and spirit so that sin does not have dominion over you, that is, that you are not governed by your evil will; if sin meets with an internal resistance of your will, being restrained and often driven away by the fear of God; if you perceive within yourself the inclination to pray, wrestle for peace of conscience, and experience the nearness of the Lord; if, either privately or in the presence of men, you desire to let your heart, thoughts, words, and deeds be governed by the will of God; if, I say, these things be in you, then you are a partaker of the spiritual life and the principle of sanctification is in you. This is not the result of your natural disposition, but a gracious gift of God issuing forth from election. Thus, you may conclude your election from this spiritual condition.
Perhaps á Brakel could have done better by expositing 2 Peter 1:5-10, his point is nevertheless made. Hearkening back to the previous two marks, it should be recognized that the force of this argument is only fully appreciated by one who has accepted the biblical teaching regarding total depravity and the spiritual death of the sinner.
The soul that is saved seeks a greater experience of that salvation.
The thought that guides á Brakel’s entire discussion of assurance is that that election is personal.
Why is the gospel proclaimed to you? Why are you called, drawn, and quickened? Why do you know Jesus and receive Him by faith? Wherefore may you have some delight in communion with God and are desirous to fear His name? Does not all of this issue forth from his eternal counsel to save you? Lose yourself in holy amazement and confess with Hagar, “Have I also here looked after Him that seeth me?” (Gen. 16:13), and with the Psalmist, “What is man, that Thou art mindful of Him?” (Psa. 8:4).
