Matthew 5, 6 & 7 is the Sermon on the Mount, arguably the strongest teaching from Jesus on how to live. Here, He corrects errors of heart. Here is the insight:
Thr Sermon on the Mount is teaching on how to obey the law (Love the Lord your God with all your heart, soul and mind and love your neighbor as yourself.) Only Jesus says to do this humbly and from the heart and WITH GRACE.
And this is the revolution Jesus led. That of grace and forgiveness, doing what is right humbly from the inside out with forgiveness.❤
