The TULIP acronym uses the expression irresistible grace. But, is grace irresistible? R. C. Sproul, a Reformed theologian wrote, "The term irresistible grace is misleading." He further wrote, "God's grace is resistible in the sense that we can and do resist it." Dr. Sproul concluded, "Thus I prefer the term effectual grace."
Scripture is clear that people resist the grace of God. "You always resist the Holy Spirit" (Acts 7:51). Scripture also speaks of those who have "insulted the Spirit of grace" (Hebrews 10:29). Until the Holy Spirit comes with conviction and changes our hearts, we resist God's grace. Thereafter, we desire to follow Christ and seek to do God's will.
Dr. Sproul used his preferred term, effectual grace. That is grace which effectively changes the hearts of people through the gospel of Jesus Christ. In the book of Acts, Lydia is an example of effectual grace. "The Lord opened her heart to heed the things spoken by Paul" (Acts 16:14). She heard the gospel, believed and was baptized.
If people resist the grace of God by rejecting the gospel, it's their choice. They are responsible for their own just condemnation. However, if people hear and believe the gospel of Christ, they do so because the Spirit of grace has worked effectively in their hearts.
