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 said, I went to the Word, reading the New Testament from 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.
