Nothing humbles and breaks the heart of a sinner like mercy and love. Souls that converse much with sin and wrath, may be much terrified; but souls that converse much with grace and mercy, will be much humbled.
God looks not at the oratory of your prayers, how elegant they may be; nor at the geometry of your prayers, how long they may be; nor at the arithmetic of your prayers, how many they may be; not at logic of your prayers, how methodical they may be; but the sincerity of them he looks at.
Christ choosing solitude for private prayer, doth not only hint to us the danger of distraction and deviation of thoughts in prayer, but how necessary it is for us to choose the most convenient places we can for private prayer. Our own fickleness and Satan's restlessness call upon us to get into such places where we may freely pour out our soul into the bosom of God [Mark 1.35].
God's hearing of our prayers doth not depend upon sanctification, but upon Christ's intercession; not upon what we are in ourselves, but what' we are in the Lord Jesus; both our persons and our prayers are acceptable in the beloved [Eph 1.6].
