The essential thing about a priest is that he mediates. He speaks to God on behalf of men and to men on behalf of God. Believers are assigned this responsible task by their God. They are to pray to God for the world. And they are to witness to the world of what God has done.
– Leon Morris on Revelation 1:6 in The Revelation of St. John (TNTC)
One reason your prayer life may be drooping is that you have neglected the Holy Scriptures. Prayer is a two-way conversation. We need to listen to God, not just talk to Him.
