The problem with the Wesleyan Holiness movement, from which much of Oneness Pentecostal doctrine originates, is that it assumes men can somehow save themselves by living perfectly, or that they can help God along in the process of sanctifying and justifying themselves.
Paul clearly states that all of the efforts of men end in failure because...
“No one is righteous—
not even one.
No one is truly wise;
no one is seeking God.
All have turned away;
all have become useless.
No one does good,
not a single one.”
Romans 3:10-12
With this in mind, every person on earth is headed to Hell. If
no one is righteous, and Paul clearly states no one
is, we are without hope.
And yet we realize that Heaven is prepared for
somebody. How then do we connect the dots between
none being righteous, and yet millions, and perhaps billions making it to the Heaven of God?
The truth is, at every person's death, no matter how well they've lived, their works are still unworthy of Heaven. At the moment of every person's death, they've fallen short of the glory of God. At the moment of every person's death, they do not deserve Heaven.
On what basis do you hope in God? What evidence leads you to believe you have a whisper of a chance of making it to Heaven?
