After which, my soul was filled with joy and peace in believing; it was a joy unspeakable and glorious, having now got good hope through grace, that though he was angry, yet now his anger was turned away, and he was now become my salvation. I rejoiced in the thoughts of my new relation to God the Saviour, and felt the ravishing sweetness of a reconciled state, and went away firmly resolving that I would walk all my days in the bitterness of my soul, and never be vainly lifted up, but would fear the Lord and his goodness, who had so far condescended to stoop so low as to pardon a rebel, and be reconciled and pacified to me after all I had done, and all my bones at this very time shall and do cry out, "Who is a God like unto thee, a God keeping covenant, and whose faithfulness and mercy endure to all generations ?" Though after this sensible and sweet covenanting with God on the hill of Craigdow, I always studied to improve this covenant relation with God, according to my various cases, tentations, necessities, and distresses, yet the most memorable time of my renewing this covenant was at Craigdarroch in Nithsdale.
In the year 1686, where in secret prayer the Lord determined to renew that covenant I had entered into with him on Craigdowhill, and wonderfully condescended to bring me as it were nigh to his seat, and filled my mouth with arguments, and allowed me to plead with him as a man does with a reconciled friend; there was I helped with great enlargement to renew and adhere to the everlasting covenant, and there the kind God manifested himself to me otherwise than to the world, and I may say that truly my fellowship was with the Father, and with his dear Son Jesus, in as sensible a way and eminent degree as ever I met with before or since, though many times he has been even since kind to my soul."
