According to Acts 26:18, sanctification is by ____.

• A. Grace
• B. Works
• C. Faith
• D. Obedience

Answer: (C)

The main idea tested is that sanctification is produced through faith in Christ. Acts 26:18 frames the process of turning people from darkness to light and from Satan to God so they may receive forgiveness and an inheritance among those “sanctified by faith that is in me.” In other words, the mechanism Jesus names for setting someone apart for God is trust in Him. Faith here is the instrument through which God’s grace works to transform a person, beginning the ongoing life of holiness. While grace enables and good works often accompany true faith, the passage specifies faith as the means by which sanctification occurs, not merely works, obedience, or universal human effort. This aligns with the broader biblical pattern that being set apart for God comes through trusting in Jesus and receiving Him as Lord.
