Neglect not the gift that is in thee, which was given thee by prophecy with the laying on of the hands of the presbytery. What is the gift? Well, there is a debate.
We don't have prophets today. We have the word of God and it's complete. ‘No need of prophets to inquire: The sun is risen; the stars retire’, as the hymn writer says. So we don't have the prophets now. Ah, but we do, because we have the Scripture, and when we appoint a pastor, we preach the promises of God to the pastor. So after all, he is sealed by prophecy. Not live prophecy, but the prophecy of the living word. Isaiah 55:10-11 is a wonderful prophecy for the appointment of a pastor, ‘For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: 11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it’ (Isaiah 55:10-11). Or we could go to 1 Corinthians 15:58, ‘Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord’ (1 Corinthians 15:58). So after all, though we don't have the live prophets like Timothy, we have the promises and prophecies of God in his word.
Timothy don't neglect the gift. How would you neglect the gift? By negligence, by carelessness, by lightness, being slipshod in preparation and study. By failing any of the departments of preaching, by failing to preach the gospel, that would be serious neglect of a vital part of the gift. By failing to teach the doctrine, by failing to exhort, by failing to lift up Christ and inspire and show the glory of things. Don't neglect any part of your commission; don't be light.
