William Carey arrived to India year 1793.He was walking by feet in the hot sun from village to village with high fever and malaria in his body Preaching the Gospel. Many times he even slept outside under a tree. After 5 years living like this Stil he hadnt seen a single convert. But his strong believe in the doctrines of Grace also called Calvinism and his strong believe in Gods Sovereignty did that he never quit preaching. After 6 years finally he saw the first Indian Guy convert. 18 Years later there were 1200 converts and baptized Indians. This can encourage us today because salvation is of the lord and we never quit preaching the gospel even if we see results or not.
I am not sure where that is quoted from but it is a misnomer. Carey was burdened by the lost souls that no one was trying to help in India and other nations. He was provoked specifically from the Moravian Missionary Magazine that showed stories of these young young missionaries giving their 100% all because of the sacrifice of Christ was for all.
He was grieved by the lack of burden amongst the baptists he was apart of. And their spirit was of such that their view of Gods sovereignty had them say to Carey: "The Lord can save the heathen by Himself" He reacted against such a spirit had displayed a missionary zeal that far out weighed many others.
He is known as the fathers of modern day missions but that is a misnomer also. The Moravians which who are chiefly unknown to modern evangelicals were the catalyst of modern missions and Count Zinzendorf himself being the father of this movement.
The moravians sent out more missionaries in first twenty years of their missionary outreaches then the rest of all the churches combined did the past 200 years prior.
