Prayer is a salve for every sore, a remedy for every malady; and when we are afflicted with thorns in the flesh, we should give ourselves to prayer. If an answer be not given to the first prayer, nor to the second, we are to continue praying. Troubles are sent to teach us to pray; and are continued, to teach us to continue instant in prayer.
Matthew HenryThough we may now think some sins light and little, if the Lord awaken the conscience, we shall feel even the smallest sin heavy upon our souls.
Matthew Henry
