For all the wells which his father’s servants had digged in the days of Abraham his father, the Philistines had stopped them, and filled them with earth. -Genesis 26:15
Therefore with joy shall ye draw water out of the wells of salvation. -Isaiah 12:3
We read that in old times the enemies stopped up the wells, but neither hell nor its infernal train can ever fill up one of the wells which the Lord has digged and filled by His Spirit. If outward ordinances be stopped, yet the great deep that lieth under will find a vent somewhere; and if we were forbidden to draw near to the Lord’s table, or to meet to listen to the word, yet, blessed be God, we could pray, and we could have secret fellowship with Jesus, and so the wells could not so be stopped that the thirsty Christian should be deprived of his drink in due season.
Moreover, as they cannot be stopped, so neither can they be taken away from us. The Philistine king, Abimelech, strove with Abraham and with Isaac to take away the wells; but these are ours by covenant engagements, these are given to us in the eternal council, they are guaranteed to us by the solemn league of the eternal Three; and none of these covenant blessings shall be wrested from the heirs of life, who are heirs of all things in Christ Jesus. ~ C.H. Spurgeon
