15 Be diligent to present yourself approved to God, a worker who does not need to be ashamed, rightly dividing the word of truth. 16 But shun profane and idle babblings, for they will increase to more ungodliness. 17 And their message will spread like cancer. Hymenaeus and Philetus are of this sort, 18 who have strayed concerning the truth, saying that the resurrection is already past; and they overthrow the faith of some. 19 Nevertheless the solid foundation of God stands, having this seal: “The Lord knows those who are His,” and, “Let everyone who names the name of Christ depart from iniquity.” (2 Timothy 2:15-19)
The Lord “knows those who are His”; they are approved before Him (verse 19, 15). We must present ourselves “approved to God” by properly handling God word to avoid error and to depart iniquity. Hymenaeus and Philetus failed to do so. They strayed from the truth and overthrew the faith of others with their error. It matters what we believe, teach and practice! If it does not, then why this warning? Clearly, here are Christians who lost their souls – not because God cannot save, but because they “strayed concerning the truth” (cf. Isaiah 59:1-2). Beware, lest you fall (1 Cor. 10:12).
