Isaiah 55 is such an inspirational chapter, consisting of an invitation and a promise, both of which are directed to us. “Come, everyone who thirsts, come to the waters; and he who has no money, come, buy and eat!” Everyone who seeks the water of life is invited to participate in this paradox of buying sustenance without money, the opportunity is not limited to Jews. We are encouraged not to spend our efforts on “that which does not satisfy”, but instead focus our attention on God. “Incline your ear, and come to me; hear, that your soul may live”.
The prophecy indicates there is a limited period of availability, “seek the Lord while he may be found”, but during this period God will show mercy, “let the wicked forsake his way, and the unrighteous man his thoughts; let him return to the Lord, that he may have compassion on him, and to our God, for he will abundantly pardon.” Seek God initially, and return when we lose our way.
There is a promise, both to the veracity of God’s forgiveness, and a future improved from the current situation. “For as the rain and the snow come down from heaven… so shall my word be that goes out from my mouth”. God’s word was not given in vain, it will accomplish His purpose of bringing “many sons to glory”. Finally, the chapter concludes with a scene of the future. “For you shall go out in joy and be led forth in peace… instead of the thorn shall come up the cypress… and it shall make a name for the Lord, an everlasting sign that shall not be cut off.”
