"Through People: "If anyone speaks, let him speak as the oracles of God" (1 Pet. 4:11). An "oracle" is an "utterance, a spokesman or mouthpiece." God speaks through preachers and teachers, but He can also speak through our spouse, kids, friends and even enemies. God uses human channels to speak words of prophecy, tongues and interpretation and words of wisdom and knowledge (1 Cor. 12:8-10). God also expresses Himself through human vessels to distribute His message in anointed sermons, songs and writings." -- Ben Godwin
God can speak through anyone; this is most definitely true. When I preached it was God and not me. God speaks through worship, pastors, prophets and all that Godwin outlines. I would just add caution here to confirm any word given by someone to you. We are all susceptible to being deceived. Any word from God must never violate His written word! This is not a pagan ritual of confirmation either. I had friends who wanted to move once to Pennsylvania and suddenly all the cars on the highway had PA license plates! Hallelujah; yeah it doesn't work that way. Again, stay tethered to the written word and you can be sure if what you are hearing from other sources is in fact from God.
"Mass Media: "This gospel of the kingdom will be preached in all the world as a witness to all the nations" (Matt. 24:14). Due to technology, this Scripture is literally being fulfilled as the gospel proliferates the globe. While Satan manipulates the media to spread his vile message like a virus, God also utilizes the media to disseminate His truth via satellite TV, radio, internet, websites, social media, books, podcasts, movies and music.
Through Creation and Nature: Psalms 19:1 proclaims, "The heavens declare the glory of God; and the firmament shows His handiwork." The vastness of space and the complexity of nature testify to God's intelligent design. You can hear the Creator's voice in a bubbling brook, in the song of a bird, in the wind whistling through the trees and in a baby's cry.
