1 And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb.
2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.
14 Blessed they that do His commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
Healing was part of Jesus' ministry:
Mat.4:23 And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people.
Mat.4:24 And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them.
Mat.9:35 And Jesus went about all the cities and villages, teaching in their synagogues, and preaching the gospel of the kingdom, and healing every sickness and every disease among the people.
Mat 12:15b and great multitudes followed him, and he healed them all;
Healing promises are still valid today:
Heb. 13:8 Jesus Christ the same yesterday, and to day, and for ever.
Mal. 3:6 For I am the LORD, I change not; therefore ye sons of Jacob are not consumed.
Mk.16:17a-18b And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
Jn. 14:12-14 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
If ye shall ask any thing in my name, I will do it.
It is God's will to heal:

Mk 1:40,41 And there came a leper to him, beseeching him, and kneeling down to him, and saying unto him, If thou wilt, thou canst make me clean.
And Jesus, moved with compassion, put forth his hand, and touched him, and saith unto him, I will; be thou clean.
