When God speaks, He speaks to edify His children for His glory. And God speaks in many different ways. This includes through His servants, the prophets.
Modern-day prophets are called to prepare God’s people by pointing them towards a more intimate and more empowering relationship with Jesus Christ (see John 3:29.) The Prophet traditionally stands in the gap between man and God (see Ezekiel 22:30), usually through intercession. However, not all intercessors are Prophets, but yet all Prophets are intercessors.
Prophets today indeed not only exist, but are needed more now than ever before to help prepare the Church body for the imminent return of Jesus Christ. Through revelation and impartation of messages through dreams, visions, words of knowledge, angelic visitations, divine encounters and yes, even by hearing the voice of God. These messages are given for the purpose of drawing, teaching, inspiring, refining, interceding as well as for warning and correcting the Church body as a whole.
“So Christ Himself gave the apostles, the prophets, the evangelists, the pastors and teachers, to equip His people for works of service, so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ. Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of people in their deceitful scheming. Instead, speaking the truth in love, we will grow to become in every respect the mature body of Him who is the head, that is, Christ. From Him the whole body, joined and held together by every supporting ligament, grows and builds itself up in love, as each part does its work.” Ephesians 4:11-13
