Throughout Jesus' mortal ministry, Jesus performed countless miracles. Of these miracles, I believe that most of them were healings, healing specific individuals of specific ailments. He healed the sick, cured blindness and diseases, including leprosy, restored mobility to the lame, cast out devils, and even raised the dead. These were all very clear and direct manifestations of Jesus' love for those people.
Yet, Jesus' healing power reaches far beyond the limits of mortal bodies and temporal lifespans. Long before He was born, and long after He died, Jesus continued to heal people, spiritually, if not also physically. I suspect that all of us have been healed by Jesus in some way or another, if only by virtue of the fact that He forgives sins.
Jesus is the Great Healer, healing people physically, spiritually, and even sometimes mentally and emotionally, and in all periods of time. And I believe that the reason Jesus heals so many people of so many afflictions is because He loves us and wants us to be happy and live well. Sometimes, there are obstacles to our happiness, and sometimes, Jesus heals us of them.
Granted, not all afflictions get healed in this life, and that it not evidence of a lack of love on Jesus' part. Quite the opposite. Jesus loves us enough to do what's best for us, eternally, even if doing so hurts us and him in the interim. Jesus wants to heal us from everything that afflicts us, but there are lessons that need to be learned, and God often allows afflictions to persist until after those lessons are learned. Sometimes, one of those lessons is patience, particularly patient endurance of affliction. Rest assured that Jesus, who felt all our pain and suffering, isn't any happier about allowing suffering to persist than we are. Jesus wants to heal us.
Thankfully, in certain ways, He often can. Jesus continues to heal wounded hearts and souls, minds and bodies, as our various circumstances allow. Healing us (eventually) of our various infirmities must be one of His greatest joys, and it's one of the many ways in which He shows His love for us.
