Is it possible for a Christian to blaspheme God?No, since God has destroyed our old will and given us His will we possess no desire to overturn all that is good in the creation. He has implanted the entire revelation. We require no one to instruct us. The bible meets our needs and is the source of Gods infinite gifts.
Therefore, we already are finished but not yet. God has implanted supreme gifts in vessels of clay. We cannot prevent God from completing the work necessary to make us like we already are. This is why growth in the Christian is by grace. We cannot offer anything to add to what God has already accomplished in Christ. Now our sloth and lack of understanding are seen by God as weaknesses. Right now our weaknesses represent our strengths. Gods grace turns weaknesses to considerable strengths. We demonstrate a creative ability to grow up or down. Grace establishes all of our motives as reasons for God to favor us. We grow up by pleading the sacred axioms. We grow down by cursing the wicked curse (which is blessing.) Pronouncing the axioms of blessing or cursing is praising and glorifying God.  We can no longer be overcome by sin and moral corruption
