Do not have your concert first and then tune your instrument afterward. Begin your day with the Word of God and prayer and get first of all into harmony with Him.
"Be careful for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known unto God." Philippians 4:6
"Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much." James 5:16
