Arminius, like Calvin and all of classical Christianity, affirmed that there is nothing humans can do to initiate salvation. Only God can do this, and God does so unconditionally, and for all, not just a limited number of the pre-selected. Christ's saving activity in his life, death and resurrection was thus potentially effective for all. Only faith, which is an exercise of our will, under the influence of divine grace, is required of us. Such faith and responsiveness to God grace, revealed in our works, but not caused by them, keeps us "in grace." This means it is possible for us to "fall from grace," a phrase he borrows from verses in Hebrews 6 and 10, by not sustaining our faith. A lapse in our works can be a sign, but again is not a cause, of such a fall from grace. The consequences, if our error is not corrected, can be spiritual death and eternity in Hell.
Though perhaps the most popular publication John Wesley produced during his lifetime was called "The Arminian," he sharply disagreed with Arminius on one point. Arminius had concluded that if a person had fallen from grace and into a state of spiritual death after having had an experience of conversion (whether that was understood to have occurred through baptism or to be heightened or awakened in a personal experience or affirmation later in life) there was no further hope for salvation. Wesley rejected this. Both experience and scripture told him otherwise. He addressed this at greatest length in his sermon, "A Call to Backsliders."
