And it was told the king of Egypt that the people fled: and the heart of Pharaoh and of his servants was turned against the people, and they said, Why have we done this, that we have let Israel go from serving us? – Exodus 14:5

(Speaking to the new converts) “A short life and a merry one,” is too often the cry of persons who are preferring death to life. The devil has the knack of making his bondsmen boast of their freedom; and they follow with eagerness that which is to their own loss and ruin. Poor slaves! their slavery has blinded their minds. Thanks be unto God, certain of you have lately fled from your former bondage; but the point I am to speak of is this-the great tyrant has not forgotten you, and he designs in his heart your capture and re-enslavement. He and his are continually looking for opportunities by which they may bring you again into the thraldom of evil, fasten the manacles of habit upon your hands, and fit the fetters of despair upon your foes. By the grace of God I hope that the Prince of evil, and his helpers, will be disappointed; but they will leave no stone unturned to effect their purposes. One of their hopes of driving you back is the belief that you are entangled by your circumstances and surroundings. They conceive that you have got into serious difficulty through your conversion, and that you cannot find your way out of your perplexity. Satan has less hope of getting back those who have escaped from his tyranny for many years. If he can trip them up or worry them, even now, he will take a delight in doing it, but he begins to see that the older pilgrims are really the Lord’s and cannot fall into his hands. Of those who have only lately escaped from his power he has greater hope, for they have not yet proved by the test of experience that the work within them is divine.

(Speaking to the older saints) It is our bounden duty to look well after beginners in the ways of God. The moral mortality in our churches is mainly among the new converts. If we leave them without help and comfort in their beginnings, we cannot tell how much they will sin and suffer. ~ C.H. Spurgeon
