God officially established healing in the church. "To each one the manifestation of the Spirit is given for the common good" (1Co 12:7). One is "gifts of healing" (:9). In this case the gift is a ministry through the one assigned. We know that you need faith to receive healing. "Faith by the same Spirit" (:9) is provided so you possess it to receive healing. You might say the gifts are interactive. Faith to operate and receive the gift of "miraculous powers" (:10) is necessary. "God has appointed . . . workers of miracles, also those having gifts of healing" (:28). "Do all have gifts of healing?" (:30). "He gives them to each one, just as he determines" (:11).
In the church if anyone is sick he should call the elders (Ja 5:14). They should "pray over him and anoint him with oil in the name of the Lord" (:14). It will heal him and "the Lord will raise him up" (:15). It is a collective endeavor to "pray for each other so that you may be healed" (:16). "The prayer of a righteous man is powerful and effective" (:16). This is illustrated in the case of a fig tree (Mt 21:18-20). Jesus told them they could "'do what was done to the fig tree'" (:21). Furthermore "'if you believe, you will receive whatever you ask for in prayer" (:22). "'Believe you have received it, and it will be yours'" (Mk 11:24). "By his wounds you have been healed" (1Pe 2:24). It has already been done and just needs to be manifested. Jesus instructed the centurion, "'Go! It will be done just as you believed it would'" (Mt 8:13). He told the woman, "'Go in peace and be freed from your suffering'" (Mk 5:34). Healing is the "'children's bread'" (Mt 15:27). Jesus answered, "Woman, you have great faith! Your request is granted.' And her daughter was healed from that very hour" (:28).
Your faith heals you (Mk 5:34). You have faith because "'My words abide in you'" (Jn 15:7). Paul said "the word is . . . in your heart" (Ro 10:8). "Let the word of Christ richly dwell in you" (Col 3:16). It "comes from hearing" (:17). Its "by the word of Christ" (:17). Its "the word of faith which we are preaching" (:8). Faith is confidence built on the trust that the word is "forever . . . settled in heaven" (Ps 119:89). Faith is inspiration because the "unfolding of Your words gives light" (:130). Therefore "walk in the Light as He Himself is in the Light" (1Jo 1:7) and it will work out.
