Rich Mullins wrote this great tune years ago which put an even older Christian creed into a melodic singable format. Years later (after Rich's death) Third Day would revamp the song, stamping it with their own southern-rocker style. The words of the song are fantastic. The theology superb. The theme--vital!
We live in the era of willfully illiterate Christianity, at least that's largely how it is here in the States. Many Americans profess Christianity, depending on which source you go to some put the number as high as nearly 75%--and yet out of that number there is an overwhelming majority of people that cannot simply and coherently explain what they believe about God, Christ, the Bible, and the Church; and there are even fewer who can effectively explain why they hold those beliefs.
Belief is powerful. It is the foundation of faith. The instigator of trust. The polar North by which we all explore our souls and do our deeds.
Even those who practice the near-militant nonreligion of skepticism are staunch adherents to what they don't believe about belief, which is only a confusing way of stating what they do actually believe.
Those of us who classify ourselves as "Believers" owe our souls, brains, conscience, and Savior--at least the simple courtesy of developing a practical means by which we can articulate, not only what we believe--but also, why we believe.
But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect... - 1 Peter 3:15 NIV
