18 For on the one hand there is an annulling of the former commandment because of its weakness and unprofitableness, 19 for the law made nothing perfect; on the other hand, there is the bringing in of a better hope, through which we draw near to God. (Hebrews 7:18–19, NKJV)
The “former commandment” is “the law” given at Mt. Sinai to Israel. God annulled (set aside, abolished) that law because it was powerless to perfect (complete) the one who comes to God. The law served its purpose of identifying sin (Rom. 3:20; Gal. 3:19). It sought to rein in Israel’s sinful conduct by teaching her holiness and the divine blessings that come from obeying God (Deut. 4:13-14; 8:1). But that covenant was temporary and “made nothing perfect” (Gal. 3:19-25). The law did not have the power to redeem souls from sin; it could not save the lost (Heb. 10:1-4, 11). It was a “shadow of the good things to come” in Jesus Christ (Heb. 10:1). Christ and His gospel (not the “former commandment”) bring a better hope to those who draw near to God for forgiveness. We dare not go back to the law of Moses to justify our worship and service to God today. To do so forfeits the grace that is in Christ (Gal. 5:3-4; 1:6-9). Remember, we are not saved by the “shadow” (the first covenant) but by the “substance” of the covenant of Christ (Heb. 10:1-4, 10-12).
39 But we are not of those who draw back to perdition, but of those who believe to the saving of the soul. 1 Now faith is the substance of things hoped for, the evidence of things not seen. (Hebrews 10:39-11:1, NKJV)
Faith that saves the soul does not draw back out of fear or neglect. It endures present trials, and by doing so receives the promised salvation (Heb. 10:36-39). This is the faith introduced in Hebrews 11:1 and described throughout that chapter. Faith is the substance of hope. “Substance” is a “setting under,” hence, faith is set under hope, supporting and stabilizing it. But, what supports and assures faith? We are told faith is the “evidence of things unseen.” Faith is conviction formed by the evidence of things that cannot be seen. For example, the swaying of the trees causes us to confidently believe in the wind, although we have never seen the wind itself. Faith concludes that “God is” (though unseen by human eyes) because this existence and order of the visible world announces His unseen presence, eternal power, and Godhood (Heb. 11:3, 6; Rom. 1:20; Psa. 19:1). Faith that God rewards those who diligently seek Him is shaped by the word of God (Heb. 11:6; Rom. 10:17; Mk. 16:20; 1 Cor. 2:10-13). Without accepting the evidence of unseen tings, there is no faith. And without faith, there is no hope. Thanks be to God who gives us evidence of His presence and the revelation of His will, so we can believe He exists and be blessed by diligently seeking Him (Acts 14:15-17; 17:22-31).
