Kenneth Scott Latorette, history Prof at Yale, said this:
“Never in so short a time has any other religious faith–or for that matter any other set of ideas, religious, political or economic–ever achieved so commanding a position in such an important culture without the aid of physical force, or social or cultural prestige.”
In other words, Christianity should NOT have spread. Islam was spread through force and conquest, especially in its early years. Not only did Christianity not have support to help it spread, there was also great persecution set against them. To be a Christian in the early church could cost you everything.
Only the Holy Spirit could make a following of a carpenter’s son grow.
Only the Holy Spirit can make us spiritually brave. The same God that stood behind the gospel in the early church still stands behind you today!
