Waste places into garden of Eden --Isaiah51

Isa51:2-3 Look to Abraham your father and to Sarah who gave birth to you in pain;...He will comfort all her waste places, and the wilderness He will make like Eden. And her desert like the garden of the Lord; Joy and gladness will be found in her, Thanksgiving and sound of a melody.

On the way to fulfilling God's calling, there's a lot of desert, a lot of waiting, a lot of pain. For Abraham and Sarah, it was 25 years, for Moses, it was 40 years of silence and harsh, dry land. But praise the Lord, nothing is wasted in Him. "He will comfort all her waste places", not only comforted, but "her wilderness He will make like Eden..." How beautiful!
For a prodigal son, we might think all those years of darkness living in sin are wasted. But when the son repent, not only did the Lord redeem, make him a success, make him a light upon the nations, make him His possession(previous notes), but also He will make all those wasted places like the garden of Eden, as if he had never sinned. How awesome is that!!
