In Acts 2:1-4 on the day of Pentecost there were two symbols that were used in connection with the Holy Spirit. A mighty rushing wind which is the breath of God. God breathed in that upper room and all the believers were filled. When they were filled tongues of fire sat upon each of them. The fire of God comes to burn up the useless things in our lives through trials and testing. Count it all joy James declares this in James 1:1-3. Welcome his breath and his fire.
