You make the most mileage by finding a faithful person and spending time with him or her until you have poured something of the life of Christ from your life into theirs.
There is such a thing as Holy Spirit endowment of power for your witness. But the other side of the Holy Spirit’s work is, “great grace was upon them all”.
It’s a great blessing to share things with people because it will confirm it in your own heart, it will give them a chance to rejoice in the Truth of God.
It is possible for you to reach a conclusion that says, “This is the will of God; and the Holy Spirit of God is witnessing with my own spirit that it is so.”
