In my view John Wesley was the greatest and most effective servant of God since the apostle Paul, and his impact has probably not been equalled since. Here is an article which was posted on Andrew Strom's revival list about this man.
JOHN WESLEY – Revivalist!
On March 9th, 1791, when John Wesley was carried to his grave,
he left behind him a good library of books, a well-worn clergyman's
gown, and a much abused reputation. But also, an England moved
to the very depths and a Church thrilled through and through with
an awakened spiritual life. John Wesley was a man who truly
possessed both apostolic vision and gifts, but most importantly
he was a man who lived in view of eternity. "Consumed by the
thought of the shortness of time, the great work to be done, and
the need for haste in doing it, on he marched, preaching, pleading,
warning and guiding . . ."
John Wesley was a man mighty in faith and prayer. Time and again
people possessed with devils were brought to him and in answer
to prayer the demons were cast out. Not only were evil spirits cast
out, but the sick were healed as well. As Wesley preached, the
power of God often came upon his listeners, and hundreds would
fall under the power of the Holy Spirit. Then, in answer, to prayer
their souls and bodies were healed. A physician became offended
at the cries of many who fell under the power of God. He attended
Wesley's meeting and a lady he knew fell under the power. "Great
drops of sweat ran down her face, and all her bones shook. But
when both her soul and body were healed in a moment he
acknowledged the finger of God." On another occasion when
Wesley was traveling the preaching circuit, his horse suddenly
became lame. With no one near to offer help, he stopped and
prayed. "Immediately the horse's lameness was gone."
Wesley pleaded with men to repent and by faith make peace with
God or suffer in an everlasting hell. People who had entertained
false hopes of salvation had their religious masks torn away by his
plain preaching. Wesley believed that those who failed to warn the
sinner and backslider, themselves stood under the judgement of
Christ. He was determined to declare the whole counsel of God,
offering the love of God in Christ and giving warning of the dreadful
consequences of rejecting the gospel. Wesley wrote, "Before I can
preach love and grace, I must preach sin, law and judgement."
John Wesley, as well as the other early Methodist preachers, was
both a bold advocate and a living example of sanctification. Wesley
preached with unceasing zeal that complete holiness was the
primary fruit of a vibrant faith in Christ. Counseling another minister,
Wesley wrote, ". . .till you press believers to expect full salvation
from sin, you must not look for any revival."
If John Wesley were to make an anonymous visit to the Methodists
of today, it is doubtful whether many of it's churches would welcome
him. They would most likely resent his fervent zeal and enthusiasm.
When he was eighty-three he made a note that he was regretful
that he could not write more than fifteen hours a day without hurting
his eyes. Wesley faithfully preached almost up to the very day he
died. Truly his vigor and zeal in old age were the reward of his
faithful stewardship of time. He seemed to consider every thought,
word and deed in light of eternity.
"Amid all his arduous labors, his innumerable engagements, his
coming and going, Wesley lived a hidden life of intimacy with God.
When worn out with overwork he often found new strength in answer
to prayer." It was Wesley's strict habit to daily spend one hour in
prayer in the morning, and then another hour in the evening. John
Wesley shook the world by his preaching because he first shook
heaven and hell with his praying. His preaching had a sense of
eternal urgency because he had touched eternity on his knees.
