Here are two testimonials of how the doctrines of Grace (especially the doctrine of election) affected and altered the life’s of two of historic Christianity’s heroes. First is a portion of George Mueller’s autobiography where he writes of his encounter with these life changing truths.
Before this period I had been much opposed to the doctrines of election, particular redemption, and final persevering grace. But now I was brought to examine these precious truths by the Word of God. Being made willing to have no glory of my own in the conversion of sinners, but to consider myself merely an instrument; and being made willing to receive what the Scriptures aid, I went to the Word, reading the New Testament from the beginning, with a particular reference to these truths.
To my great astonishment I found that the passages which speak decidedly for election and persevering grace, were about four times as many as those which speak apparently against these truths; and even those few, shortly after, when I had examined and understood them, served to confirm me in the above doctrines.
As to the effect which my belief in these doctrines had on me, I am constrained to state for God’s glory, that though I am still exceedingly weak, and by no means so dead to the lusts of the flesh, and the lust of the eyes, and the pride of life, as I might be, and as I ought to be, yet, by the grace of God, I have walked more closely with Him since that period. My life has not been so variable, and I may say that I have lived much more for God than before.
And here is a section from Spurgeon’s autobiography of how the doctrines of Grace changed this great preacher.
When I was coming to Christ, I thought I was doing it all myself, and though I sought the Lord earnestly, I had no idea the Lord was seeking me. I do not think the young convert is at first aware of this. I can recall the very day and hour when first I received those truths [the doctrine of election] in my own soul – when they were, as John Bunyan says, burnt into my heart as with a hot iron, and I can recollect how I felt that I had grown on a sudden from a babe into a man – that I had made progress in Scriptural knowledge, through having found, once for all, that clue to the truth of God.
One week-night, when I was sitting in the house of God, I was not thinking much about the preacher’s sermon, for I did not believe it. The thought struck me, How did you come to be a Christian? I sought the Lord. But how did you come to seek the Lord? The truth flashed across my mind in a moment – I should not have sought Him unless there had been some previous influence in my mind to make me seek Him. I prayed, thought I, but then I asked myself, How came I to pray? I was induced to pray by reading the Scriptures. How came I to read the Scriptures? I did read them, but what led me to do so? Then, in a moment, I saw that GOd was at the bottom of it all, and that He was the Author of my faith, and so the whole doctrine of grace opened up to me, and from that doctrine I have not departed to this day, and I desire to make this my constant confession, “I ascribe my change wholly to God”.
