God be merciful to me a sinner was the cry of John Warburton on discovering and realizing he ruined lost condition before God. He knew and felt the condemnation of God against him. He knew of no way but to mend his ways, repent to find mercy. He could think of no other way to save his soul but by mending his life, doing his duty and pleasing God. This book, "Mercies of a Covent God" tells the life story of John Warburton, of his call by grace, and becoming a Particular Baptist minister in England. This book is not dry or intellectual Calvinism but experiential Christian experience. Teaching the way of salvation as God's way, Father, Son and Holy Spirit engaged in covenant to save, not merely to propose salvation but to call by grace. Faith alone in the person of the Lord Jesus Christ, his atoning blood, and imputed righteousness are clearly taught to be blessings of grace. The soteriology of John Warburton, like all Particular Baptists is Calvinistic, but not dry textbook Calvinism. True religion is more than notion, something must be known and felt.
