Setting aside the miracles of the universe and life, the arguments from miracles and providence refer to more specific examples of things that could not have happened without God’s influence.
Miracles are understood by supernatural works by God. If miracles occur at any point in history, God must be the cause. Multiple miracles have occurred over the course of human history. Therefore, God exists.
Argument from Providence
God’s working can be seen in history, through the working of Scripture, and through the working of individuals. God’s existence is the only possible explanation of these occurrences.
Argument from the Saints
If something is positively different about authentic religious people than those who are not, there must be a reason. If the positive results are shown to be from God, then God must exist. Authentic religious people are different than unbelievers. Many show changes and possess strength that could only be attributed to the divine. Therefore, God exists.
This is similar to the argument from the saints. There are several individuals throughout history who have experienced a 180 degree turnaround. Atheists and antagonists to the Christian faith have become Christians due to personal encounters with God. God’s existence is the only rational explanation for these occurrences.
NDE and OBE Argument
Since there are several occasions where people have experienced God after death, and there have been occasions where these experiences have been medically confirmed (for example, individuals who have witnessed and confirmed events and objects after being pronounced dead, then being allowed to come back to confirm the events and objects), the existence of God and the afterlife are the only rational conclusions. See the works of J. P. Moreland and Gary Habermas for greater detail of such occurrences.
