Our prayers have stains in them, our faith is mixed with unbelief, our repentance is not so tender as it should be, our communion is distant and interrupted. We cannot pray without sinning, and there is filth even in our tears.
The saints are sinners still. Our best tears need to be wept over, the strongest faith is mixed with unbelief, our most flaming love is cold compared with what Jesus deserves, and our intensest zeal still lacks the full fervor which the bleeding wounds and pierced heart of the crucified might claim at our hands. Our best things need a sin offering, or they would condemn us.
We must keep from sin. If Christ has indeed saved us from sin, we cannot bear the thought of falling into it. Those who take delight in sin are not the children of God. If you are a child of God, you hate it with a perfect hatred, and your very soul loathes it.
Author: Charles Spurgeon Source: Spiritual Warfare in a Believer's Life, Sermon Matthew 4:4.
When men talk of a little hell, it is because they think they have only a little sin, and believe in a little Saviour; it is all little together. But when you get a great sense of sin, you want a great Saviour, and fell that, if you do not have Him, you will fall into a great destruction, and suffer a great punishment at the hands of the great God.
You and your sins must separate or you and your God will never come together. No one sin may you keep; they must all be given up, they must be brought out like Canaanite kings from the cave and be hanged up in the sun.
