It is tempting to trust in our spiritual heritage for divine approval. We can put our confidence in our parents’ faith without developing our own. Merely trusting in a spiritual heritage is a futile and fatal approach to our present faith and future hope. John the Baptist’s preaching reminded his audience to take a personal inventory of their hearts and lives. This reminder still holds. He warned the Jewish people not to put their confidence in their ancestral heritage. It was God who chose Abraham and blessed him for his faith (Gen. 12:1-3; 15:6). God must be trusted and obeyed because His purposes prevail. His judgment of Israel was imminent when John preached (“the ax is laid to the root of the trees”). God’s judgment destroys the unfruitful (those who do not repent and bear its fruits). Repentance is a change that takes place in the heart. It is a fundamental reordering of perspectives and priorities to put away sin and do God’s will (Lk. 3:10-14). Repentance is not being sorry for our iniquities; it results from godly sorrow (2 Cor. 7:9-10). Without repentance toward God and faith in Jesus Christ, we cannot bear good fruit (Acts 20:21). But, when we change our hearts toward God (repent), we will conform our lives to His will – “bear fruits worthy of repentance.”
