Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, “Vengeance is Mine, I will repay,” says the Lord. “But if your enemy is hungry, feed him, and if he is thirsty, give him A drink; for in so doing you will heap burning coals on his head.” Do not be overcome by evil, but overcome evil with good. Romans 12:19–21, NASB
It is the duty of all believers to serve the Lord by being good soldiers, ready for battle to stand and contend for His Truth no matter the cost. However, there are right and wrong ways this is done. It is vital for the apologist to know the truth, and that is found only in God’s Word. Yes, some godly Christians speak and write truth from God’s Word, but the primary source for us is the Word of God. This is why it is vital that believers sit at the feet of good and godly teachers of God’s truth that they may know and love His pure doctrines. I have seen so many good Christians attempt to stand up to apologists for some man-centered version of our faith, but they are not prepared. This usually ends badly. The reason this happens is that these good people use tactics born in the flesh rather than from the humble, and wise heart that is submitted totally to the will of God. The enemy is an expert at inciting people to react emotionally to what they perceive as wrong, and this can lead to snippy arguments that produce only bad fruit.
