First of all, our physical condition is not God's primary concern. Ouch. Our Father's first priority is to prepare us for eternity because, face it, eternity is much longer than the few short years we have here. He is more concerned about our heart condition, the shape of our soul, the relationship we have with Jesus. When Jesus stepped into the public light and became anointed with the Spirit, his priority was not healing but the casting out of demons and the preaching of the Good News. When his twelve disciples came back from an outing he sent them on, and they were all excited because they had healed people and cast out demons, Jesus told them to be more excited about their names being written in the Lamb's Book Of Life. When the paralyzed man was lowered down through the roof to get to Jesus, Jesus' first reaction was not to heal him but to forgive his sins. Healing came after.
Yet, Jesus could not walk through the cesspool of humanity without being moved by man's condition, both spiritually and physically. He taught to open our eyes, but he healed out of simple compassion. God loves us. He cares deeply about us. His priority for us is eternity but he is stilled moved by the condition we live in, the diseases that attack us. So Jesus equipped his people to continue to act in compassion, to do what he did, to reach out in love, to bring relief to a suffering humanity. Look at his compassion. It is everywhere you read in the gospels, it became a big part of what Jesus did.
So why doesn't God heal everyone? people ask. In compassion I believe God is willing to heal everyone, but not everyone is willing to accept it. Believe it or not, it is possible to refuse things from God. It is possible to say no to God. We can do it without even realizing we are doing it. We do it with the simplest thought of doubt. If we can refuse the greater blessing of salvation then it is a simple matter of turning away the blessing of healing. Just as it requires faith to accept Jesus and receive salvation, it requires faith to be healed. The thing is, I don't think the probably is needing to be convinced God heals but instead that God loves us.
Most people miss out on the many blessings of God because they are not convinced that these blessings are meant for them. They feel, knowingly or unknowingly, that there is something about them that disqualifies them from God's love. They believe God loves everyone else but not them; that they are not deserving of that love. Ha! The cold hard fact is that none of us are deserving of his love, but that hasn't stopped him from loving every single person on the planet, regardless of their actions. He loves us and Jesus dying in our place is proof of that, but until we are absolutely convinced of this love, and understand the completeness of this love; I mean the absolute completeness of it; we will continue to refuse certain blessings God wants us to have.
His priority is eternity for us but if he has given us his very best, does it not make sense that he will not refuse us any good thing? God is not roaming around to see who he can heal because he is occupied with our eternity. Jesus did not walk around looking for people to heal, but when he was asked to heal he said he was willing and acted upon his compassion. If we ask, knowing that he is willing, then we will see him act in compassion. I am not saying people lack faith necessarily but it is more a lack of understanding of God's compassion and his willingness. He has even empowered us to be vessels of healing. We need to discover more about his heart by descending deeper into his love.
I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love, may have power, together with all the saints, to grasp how wide and long and high and deep is the love of Christ, and to know this love that surpasses knowledge—that you may be filled to the measure of all the fullness of God.
Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work within us, to him be glory in the church and in Christ Jesus throughout all generations, for ever and ever! Amen. (Ephesians 3:16-21)
