Why do some people readily respond to the gospel of salvation? Why do some people reject the gospel and refuse to believe it? The answer is not due to any deficiency in the gospel itself. The gospel is not a distant, inaccessible, and undiscernible message. It has been preached openly to the world (Rom. 10:6-8; Eph. 3:3-5). The answer lies in the heart of the hearer. Isaiah wrote of the dull hearts, heavy ears, and closed eyes of Israel (Isa. 6:9-10). Jesus applied the prophet’s words to His generation (Matt. 13:13-15; 15:7-9). Christ also taught parables that illustrated hard hearts that prevent the gospel’s penetration and saving power (Matt. 13:18-19). Do not marvel when the truth of the gospel is rejected, scorned, and denounced. The problem is not the word of salvation; it is the solution (Rom. 1:16). Honest and good hearts receive the word of God, “keep it and bear fruit with patience” (Luke 8:15).
