6) Jesusí death on the cross provided a penal substitutionary atonement for the sins of humanity. In salvation we are rescued from Godís wrath by His unmerited grace alone, through faith alone, on account of Christ alone.
Again, Alan--Walter Martin preached a faith alone theology--which states one is saved by God's grace--through a faith without works. IOW--dead faith saves, in the faith alone theology:
James 2:26---King James Version (KJV)
26 For as the body without the spirit is dead, so faith without works is dead also.
