“…I will give unto him that is athirst of the fountain of the water of life freely.” -Revelation 21:6

The simplest thing in all the world is just to look to Jesus and live, to drink of the life-giving stream, and find our thirst for ever assuaged. But though it is so plain that he who runs may read, and a man needs scarce any wit to comprehend the gospel, yet we went hither and thither, and searched for years before we discovered the simplicity which is in Christ Jesus…Ah! the methods and the shifts we will be at to try and save ourselves, while, after all, Christ has done it all. We will do anything rather than be saved by Christ’s charity. We do not like to bow our necks to take the mercy of God, as poor undeserving sinners. Some will attend their church or their chapel with wonderful regularity, and think that that will ease their conscience, and when they get no ease of conscience from that, then they will try sacraments, and when no salvation comes from them, then there will be good works, Popish ceremonies, and I know not what besides. All sorts of doings, good, bad, and indifferent, men will take to, if they may but have a finger in their own salvation, while all the while the blessed Saviour stands by, ready to save them altogether if they will but be quiet and take the salvation He has wrought. All attempts to save ourselves by our own works are but a base bargaining with God for eternal life, but He will never give eternal life at a price, nor sell it, for all that man could bring, though in each hand he should hold a star; He will give it freely to those who want it. He will dispense it without money and without price to all who come and ask for it, and, hungering and thirsting, are ready to receive it as His free gift, but –

“Perish the virtue, as it ought, abhorred,
And the fool with it, who insults his Lord,”

by bringing in anything that he can do as a round of dependence, and putting that in the place of the blood and righteousness of the Lord Jesus Christ. ~ C.H. Spurgeon
