Why is it you think he's petty and small???
Maybe you could rephrase that question, God uses many means to bring people to the truth of who he is, but that truth is only found in Christ.
The Holy Spirit is the one who leads men to Christ.
But God knows that men would not accept his way, but introduce their own alternate methods that may tend to justify and gratify their carnal practices.
Why....
Jhn 7:7The world cannot hate you; but me it hateth, because I testify of it, that the works thereof are evil.
People need to understand that without the shedding of blood there is no forgivenesss of sins.Blood was the means in which God would redeem men,but not just any man's blood,it had to be pure and holy.
Jesus Christ was that perfect,sinless sacrifice that would atone the sins of men when it was spilled, but, through his death he also defeated death and brought life and immortality by his resurrection to those who receive him.
.......but
Jhn 3:19And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
