God occasionally used visions to reveal His truth as He did with Peter (Acts 10:9-16) and Paul (Acts 16:9-10), but they were never His primary means of communication. Since the completion of the Bible, God now speaks to us through His written Word and the guidance of the Holy Spirit (2 Timothy 3:16-17; John 16:13). While God may still use visions in rare circumstances, especially in unreached regions,we must rely on what we do know and have, like God’s Word, for the foundation of our faith (Psalm 119:105; Romans 10:17). Visions must align with Scripture, and those that contradict Scripture must be rejected, as deception can come through false teachings, emotions, or even demonic influence (Galatians 1:8; 2 Corinthians 11:14). Believers are called to test everything against the truth of Scripture, which remains our sure and sufficient guide (1 Thessalonians 5:21).
Not all visions are from God. Visions can be real and really false at the same time. Buddhism was heavily informed by a vision Siddhartha Gautama had while sitting in a trance. In the time since the Bible was compiled, many visions have directly contradicted Scripture. The false teachings of Islam, Mormonism, and the Unification Church were all begun by people who had visions. To discern a vision's origin, believers must prayerfully evaluate it using the Bible as the standard, seek counsel from spiritually mature believers, and examine the vision’s message for fruit that reflects the Holy Spirit—such as truth, peace, humility, and the glorification of Christ (Galatians 5:22–23; John 16:13–14).
If a vision isn't from God, where does it come from? There are several possibilities. It could just be a lie, concocted by a charlatan to serve his own purposes. It could be a case of lucid dreaming/false awakening, where a sleeping person feels awake and can control his dreams to some extent. Or it could be drug-induced; hallucinogenic drugs are often taken for the specific purpose of experiencing visions. And, of course, a person may have a vision he thinks is from God but is actually demonic in origin (1 Timothy 4:1). Satan wears masks (2 Corinthians 11:14).Is it possible God could still give visions? Of course. Does He? Perhaps, but not to the degree He once did. Scripture is complete. Visions were generally given when Scripture was incomplete. Today, most of the authentic visions occur in areas that have not yet been exposed to Christianity or where the Bible is suppressed.We must be wary when someone claims to have received a vision from God. Modern-day prophets are easily deceived by the "delusions of their own minds" (Jeremiah 14:14 NIV), and we are not to follow false teaching (Jeremiah 23:16). Any vision that contradicts Scripture should be immediately rejected.
