When we presume something, we are not taking into full account what we don’t know. Presumptuous sin is first a thought. We have the choice to continue processing the thought or stoping it. Always it is a choice to sin or not.
This is brought home to me every time I read the account of Simon. Acts 8:20 says, “…you thought that the gift of God could be purchased with money!” Verse 22 gives us direction when we have an enemy-thought. It says, “Repent therefore of this your wickedness, and pray God if perhaps the thought of your heart may be forgiven you.”
We have an OT example through Nebuchadnezzar. Daniel 4 is the narrative. Nebuchadnezzar had two dreams that Daniel interpreted. In verse 27 said, “…break off your sins by being righteous…” However in verse 30 the king verbalized his thoughts. He was glorying in his own accomplishments. Verse 31 says that while the words were still in his mouth, the Lord told him that his kingdom was over. God then humiliated him UNTIL. Verse 32 says that he would know the Most High rules.
Unrighteous thoughts exalt us, whereas righteous thoughts exalt the Lord. It is prudent for us to humble ourselves before Him, rather than Him having to humble us.
Presumptuous thoughts are inflated with pride. 2 Corinthians 10:5 says to cast them down because they are against the knowledge of God. Take up the sword of the Spirit and pierce your pride-thought. Deflate it by bringing your thoughts into alignment with God’s thoughts. John 15:5 is a great one. “…without Me you can do nothing.”
