Be warned, miracle-mongers, though some of the miracles in the OT, like protecting the men in the kiln, or closing the lions' mouths were to the good for those who loved Him, "most of the miraculous events in the Old Testament killed people." Most of the miracles in the OT (and some in the NT- Ananias, Sapphira) simply, flatly, killed people, as a demonstration of God's justice and holiness.
John MacArthur preached,
His justice is demonstrated at the cross. It is God who said the soul that sends it must die. It is God who says the wages of sin is death, and death there will be. Death there must be. And justice prevails at the cross. God is so just, so just, that He will even take the life of His own beloved Son. If the sins of the world are to be laid on His Son, then His Son must take the death that they deserve. You will never see a greater illustration of the justice of God. You can look in the past. You can look in the Old Testament. You can see most of the miracles in the Old Testament killed people. If you’re looking for miracles in the Old Testament, most of the miraculous events in the Old Testament killed people, drowned entire armies, drowned the entire world, burned up people, holes opened in the ground and swallowed them up. People were literally killed by angelic beings. Most of the Old Testament miracles were miracles of divine judgment.So Jesus said to him, "Unless you see signs and wonders you will not believe." (John 4:48)
Do you love Jesus for who He is? Or for what He can do for you? A warning to those who seek and cling to and desire miracle after miracle, be careful what you wish for--
For false Christs and false prophets will appear and perform great signs and wonders that would deceive even the elect, if that were possible. (Matthew 24:24)
