You despise and reject the testimonies because they reprove your darling sins and disturb your self-complacency. When Christ is cherished in the heart, His likeness will be revealed in the life. Humility will reign where pride was once predominant. Submission, meekness, patience, will soften down the rugged features of a naturally perverse, impetuous disposition. Love to Jesus will be manifested in love to His people. It is not fitful, not spasmodic, but calm and deep and strong. The life of the Christian will…
"And thou shalt remember all the way which the Lord thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thine heart, whether thou wouldest keep his commandments, or no."
