People ask me how I "hear" God. As a Catholic, God speaks to me through the Catholic Church's wonderful teaching, and, of course, through the Mass.
God speaks to all of us through the Scriptures, the daily readings, the Divine Office.
God speaks to us through the meditations of the rosary.
God speaks to us through the events of our lives, and through other people we meet.
The gift of listening must be developed in prayer and in the daily events of our lives.
But, rarely, God speaks to us directly. And, this is rare. I can count on one hand the times I have "heard" God directly. And, the reasons He did this was to get my attention and to emphasize a point. Some of us suffer from self-doubt when we think we are perceiving God in prayer. But, on those rare occasions when God "speaks" and one "hears", one cannot doubt the Voice of God.
We must not compare ourselves with other people either in prayer or in the events of our daily lives. To compare is a useless endeavor, as each one of us is unique and God deals with us all uniquely.
A spiritual director would help, of course, but many cannot find one. Good friends who are solid, orthodox Catholics can also help us discern the Voice of God. Sometimes, someone holy will tell us the same thing we think we heard from God.
Pray for clarity.
