In our churches today, nearly every time we minister healing for a sick person it is usually for someone who is already a saved believer. Jesus, however, did not come to heal sick believers. There were no believers when he appeared. Rather he healed the sick—most often unbelievers—for the primary purpose of convincing them to believe on Him as the Messiah, the Son of God. Miraculous healings comprised most of the miracles Jesus performed in the gospels and Acts.
John 20:30 Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. 31 But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.
John 14:11 Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the works themselves.
The only two references to healing for believers in the New Testament are in 1 Corinthians 12 where Paul lists the gift of healing to be used to build up the Church and in James 5:15 where it is taught that “and the prayer offered in faith will make the sick person [that is, believer] well; the Lord will raise them up.”
By contrast, the very many miraculous healings recorded in the gospels and in Acts were performed overwhelmingly for the very purpose of bringing sinners to Christ as Lord and Savior. Sadly, the Church has forgotten this and sees miraculous healing overwhelmingly as a blessing for believers. The focus is nearly always on those who need healing in the Church, and miraculous healing as a sign to draw the lost to Jesus is hardly ever seriously considered.
Is it therefore any surprise why so few believers in the Church are miraculously healed as recorded in the gospels and Acts? If the Church placed the primary emphasis on winning the lost as in Scripture, we would witness many more miraculous healings for infirm believers.
