He will not get away with it.
Everyone is accountable and the evil aggressor will have to answer to what he has done.
God “will repay each person according to what they have done.” (Romans 2 v 6)
Paul probably has one of these verses in mind or all of them:
Proverbs 24:12 “Will he not repay each person according to what he has done?”
Psalm 62:12 “Surely you will reward each person according to what he has done”
Hosea 12:2 “The Lord … repay him according to his ways.”
That repayment is either in our lifetime but definitely when we stand before Him.
What we do during our lives matters.
How we live today, the choices we make, the responses we give, the deeds we commit, we are accountable for our actions.
Sobering but true.
