People frequently refer to God’s calling them by a variety of means. God calls us "by the gospel" and in no other way. God does not speak to us through other means today, only through the word of God. The proof of this belief is found in the conversions in the book of Acts. In all cases of conversion, the gospel is carried forth and proclaimed by a third party.
