But whoever drinks of the water that I will give him will never be thirsty forever.John 4:14
The person who believes in Jesus finds enough in his Lord to satisfy him now and to content him forevermore. The believer is not the man whose days are weary for lack of comfort and whose nights are long on account of the absence of heart-cheering thought. The believer finds in faith such a spring of joy, such a fountain of consolation that he is content and happy. Put him in a dungeon, and he will find good company; place him in a barren wilderness, and he will eat the bread of heaven; drive him away from friendship, and he will meet the "friend who sticks closer than a brother."1 Destroy all his shade, and he will find shadow beneath the Rock of Ages; erode the foundation of his earthly hopes, but his heart will still be fixed, trusting in the Lord.
The heart is as insatiable as the grave until Jesus enters it, and then it becomes a cup full to overflowing. There is such a fullness in Christ that He alone is the believer's sufficiency. The true saint is so completely satisfied with the provision of Jesus that he no longer thirsts--except perhaps to drink more deeply at the living fountain.
In that sweet manner, believer, you will thirst; it will not be a thirst of pain, but of loving desire; you will find it a sweet thing to be longing for a deeper enjoyment of Jesus' love. An old saint once declared, "I have been lowering my bucket into the well so often, but now my thirst for Jesus has become so insatiable, that I long to put the well itself to my lips and drink right out of it."
Is this the feeling of your heart now, believer? Do you feel that all your desires are satisfied in Jesus and that you have no need now except to know more of Him and to have closer fellowship with Him? Then come continually to the fountain, and take the water of life freely. Jesus will never think you take too much but will always welcome you, saying, "Drink; yes, drink abundantly, loved one."
