O, has not some secret evil been in operation to cool our love, to abate our zeal, to separate us from our heavenly Father's smile?
Is it the love of the world?
Is it the love of the creature?
Is it ambitious designs, or sensual indulgence?
Search us, O God and enable us to search ourselves.
Mark 12:30 ... And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
