Isaiah 55:1-4 "Come, everyone who thirsts, come to the waters; and he who has no money, come, buy and eat! Come, buy wine and milk without money and without price. (2) Why do you spend your money for that which is not bread, and your labor for that which does not satisfy? Listen diligently to me, and eat what is good, and delight yourselves in rich food. (3) Incline your ear, and come to me; hear, that your soul may live; and I will make with you an everlasting covenant, my steadfast, sure love for David. (4) Behold, I made him a witness to the peoples, a leader and commander for the peoples.
Writing on to the new covenant people… We learn in Acts that David was a man after God’s own heart. What was it about David? First and foremost it was his faith in God’s love and protection. He was set apart to be a commander of the people and a type of Christ. It is through the linage of David that the kingdom of God gets its king. The kingly prophesies of Christ Jesus always included David.
The interesting thing about this prophecy is who is addressed… “come EVERYONE who thirsts” It is not just a promise to the nation, natural Israel. It is a promise to everyone, Jew or gentile who thirsts. Jesus said the following: Matt 5:6 "Blessed are those who hunger and thirst for righteousness, for they shall be satisfied.” He is explaining what was meant by Isaiah 55:1. Thirsting for righteousness is really thirsting for justice. It is one who desires in his or her heart to be just and righteous. That will be the trait of new covenant people. Even when they fall short, none the less they still thirst for righteousness.
I have known addicted people, that is, people with addictive personalities hunger and thirst for righteousness. Conversely, I have known many who think that they have achieved righteousness by their behavior that have no apparent hunger or thirst. Remember Jesus’ parable about the two that went to the temple to pray… I would sincerely watch thanking God for helping us to be righteous. What we need to do is thank God and rejoice for declaring us righteous right where we are!
Further down the passage in Isaiah, we Gentiles are included in the promise of Isaiah 55. Isaiah 55:5 Behold, you shall call a nation that you do not know, and a nation that did not know you shall run to you, because of the LORD your God, and of the Holy One of Israel, for he has glorified you. Here again is ample proof that the new covenant people are neither Jew nor Greek, male nor female, but rather, a new creation/creature.
Right now, if you are struggling day by day, but if in your heart you hunger and thirst for righteousness… like for a cold drink and a plate when you are parched and hungry, know this, you will be filled. New Covenant People are filled by the blood of Jesus Christ and that makes them love… they love God… they love each other… and they love and seek everyone who hungers and thirsts.
