Jesus began giving examples of the spirit of God’s word (39):
God’s word says, do not murder another person.
But I say, do not even indulge in anger toward another person. That’s the same as committing murder in your heart!
So, if you’re about to worship God in any way, and you remember an unsettled dispute with another person, first go & make peace with that person, and then return to worship God.
For example, if someone brings a lawsuit against you and is taking you to court, settle the dispute with him before you get to court. Make that a priority before God.
(39) Matthew 5:21-26
