Good music played and sung from the heart moves God, the creator of the whole universe! Read 2 Chronicles, chapter 5 verses 12 to 14 of the holy bible and see the power of music. There lies the proof that good music offered in praise to God brings down God's glory.
If music moves God and man, it is then a very efficient way of communication between the two. Therefore the word of God set in musical form will go a long way in touching people's heart, even more than the verbal preaching. Preach the word of God to a downcast man, he may or may not be disposed to listen to you, but set the same message into beautiful music and play it to the hearing of the same man and you will be surprised to see him consciously or unconsciously savouring the tune by nodding or stamping of the feet or even by singing along! What a wonderful way of bringing a downcast soul to God.
A jailer was saved and converted with his household because his prisoners, Paul and Silas, prayed and sang praises to God whose glory came down and shook the foundations of the prison and liberated the prisoners(read Acts 15:25-34).
Perhaps you may have wondered why churches and crusade organizers spend so much money on musical groups such as choirs,bands and orchestra. It is because they understand that the best way to reach human soul is through music. Incidentally, that is also the best way to reach God. If this is so, then Gospel music is an inevitable medium to spread the good news of our Lord Jesus Christ as he has commanded us to do in the bible(Matthew 28:19-20).
Are you a gospel musician, singer or gospel artist? Be encouraged because you are doing a wonderful work of an evangelist. Are you in any way involved in the promotion of gospel music? Do not despair because you are already a part of that Great Commission or rather the Supreme Commission as Evangelist Reinhard Bonnke of Christ For All Nations use to call it.
Remain blessed in Christ Jesus!
