I think we need to be immensely careful here.
The Lord says the sheep know the Shepherd's voice, but some have wrongly taken from that to mean that God literally speaks to them, either as a voice in their head, or a feeling.
That's really dangerous, it's a mode of thought that easily leads toward spiritual delusion. Perhaps even inevitably so.
The sheep know the Shepherd's voice because His word is Gospel, and we have heard the Gospel and believed. The Shepherd's voice is His word, and His word is not in secret, but is publicly declared. It's right there in what has been written for us, it's right there in the very public preaching and ministry of the Church. It is the proclamation of the Gospel, the administering of the Sacraments. It's what we have heard and received since the beginning.
And that's really so important, it's the difference between, "The word of the Lord, blessed is the name the Lord." and "I feel that God is telling me..."
I get it, like, it's really exciting to think that maybe I can have this direct conduit to God, and God is going to talk to me directly somehow. Maybe if I just try really hard then I'll be holy enough that I might receive a vision from Him, or a dream, or maybe these feelings I have right now are actually God prompting me. It's all very exciting, all very sensational. But that stuff is just inert gas. It doesn't mean anything. And, more dangerously, this is the stuff the devil uses to choke our faith.
The devil isn't going to come at you looking like Freddy Kruger from the Nightmare on Elm Street movies, he's going to come to make you feel better about yourself, make you feel more spiritual. Or maybe, make you feel worse like you don't measure up. Either way works for him, what difference does it make if you believe yourself beyond the hope of redemption, or if you are so puffed up in your own sense of spirituality and piety that you can't be bothered to repent and confess your a sinner. Either way, you are being turned away from the Gospel, turned away from Christ--His cross and empty tomb.
I'm not saying the devil is giving you or any specific people false visions; but, even the product of our own minds can be turned against us. I may not need the devil to tell me I'm a dirty rotten sinner who has sinned too much to be loved by God, my own despairing flesh does that, but then the devil and my flesh are natural allies anyway, right?
Therefore turn your gaze to Jesus. Let us always have our eyes upon Jesus. Cast off those weights, trust in the One whose flesh was pierced and blood was shed, who descended into hell to cast down hell, crushing the devil, defeating death, reconciling us to God, and rising as the One who is alive forever and ever, who holds the very keys of death and hades in His hands.
Behold the Lamb of God who takes away the sins of the world!
