About the Contributor(s): Robert B. Callahan Sr. founded Callahan & Associates, Inc., in 1976, a telecommunications consulting firm. He is the author of The Triune God Speaks to the Saints, Volume 1 in an eight volume expository commentary on the Apostle Paul's epistle to the Ephesians.

The Triune God speaks to the saints and in so doing proclaims God's will and the spiritual blessings available from Him, His Son, and the Holy Spirit. It starts with doctrine, God's call, Christ's teachings, trusting Him, and knowing the Word. The Word is essential, it needs to be the whole Word of God revealing His being, nature, teachings, and commands. It culminates in stressing the importance of prayer, in giving thanks, receiving wisdom in the knowledge of Him, being enlightened, knowing the hope of His calling, and believing in His mighty power as we walk through life with Jesus encountering its trials, tests, and tribulations as well as experiencing its joys, blessings, and gifts with a grateful heart.
