It cannot of course be proven scientifically that God exists, and that there is a heaven and a hell as taught by the Bible. Such are to be accepted by faith alone.
However, there is a teaching in the Bible which can empirically be proven to be valid. If we analyze closely how Jesus healed the sick and cast out demons as recorded in the gospels, we will arrive at certain principles regarding exactly how He performed such miracles.
And in John 14:12 Jesus declared “Very truly I tell you, whoever believes in me will do the [miraculous] works I have been doing…”
According to John 14:12 above, if believers minister to the sick and demonized exactly as Jesus did, they will be miraculously healed and set free.
We have seen and are seeing that when the gospel is being preached and believers minister to those with infirmities exactly as Jesus did as recorded in the gospels, the infirmities are miraculously healed. On occasions these miraculous healings have been confirmed by medical doctors.
This can be considered empirical evidence that the words of Jesus in John 14:12 above are in fact true. Since John 14:12 can be verified as being valid, can we also conclude that Jesus’ extraordinary claim in John 14:6 below is also valid? Can someone who performed such unprecedented miracles and spoke with wisdom that no man had never spoken with before be a liar or a lunatic?
John 14:6 “I am the way and the truth and the life. No one comes to the Father except through me.”
