The joy which answers to prayer give, cannot be described; and the impetus which they afford to the spiritual life is exceedingly great. The experience of this happiness I desire for all my Christian readers. If you believe indeed in the Lord Jesus for the salvation of your soul, if you walk uprightly and do not regard iniquity in your heart, if you continue to wait patiently, and believingly upon God; then answers will surely be given to your prayers.
