A.W. Tozer warns against the heresy that arises when the Christian church adopts a distorted view of God, leading to a tragic decline in the understanding of His majesty and presence. He emphasizes that substituting lofty concepts of God with low and ignoble ideas results in a moral calamity for believers, ultimately diminishing the appeal of Christianity. Tozer asserts that the true nature of God must be upheld to avoid the insidious consequences of heresy, reminding us that true transformation comes only through being 'born again' in Christ.
