When Paul had been abandoned by Demas because he loved the present world. He could not endure the hardships of the ministry. Just as Paul, when our friends that start out with us is no longer faithful on the missionary journey it cause us to want to here encouraging word from other friends who have not abandoned their faith in Jesus Christ. The Lord is faithful, Paul stated in (V 17a).
But the Lord stood with me and strengthened me, The Lord is always their for the asking, Praise The Lord, Thank you Jesus, and bless His Holy Name.
