When you receive a call from God, but you see no way to fulfill it, determine that you will not be a quitter. Stay with God and be filled with the Living Water of Christ at the fountains of grace. Do not be a coward who backs off with excuses and becomes a spiritual wimp with a Laodicean attitude. Some people leave their call and think they are going for something bigger and better. They will never find it!
What does the Lord desire for us? Salvation? Yes. But Jesus Christ wants all men to be able to think with God's thoughts and God's ways, from a divine viewpoint. He would have all men to come to a knowledge of doctrine by experience through learning, believing, receiving, and living it out.
When the living God controls your thirst, then you share Him with others. The river flows from the heart, in the mind, to the emotions, and then it goes out. Not down, but out! And the spring goes up, because you are always satisfied. Is it any wonder that in Psalm 42:2, the psalmist said, "I thirst for the living God"? Is it any wonder that Matthew 5:6 says they that hunger and thirst, and continue to thirst, after righteousness shall be filled continuously?
