““Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account.” (Matthew 5:11, ESV) To be blessed is to be happy and typically we don’t associate ‘happiness’ with being cursed and put upon by others – especially because we have faith in Jesus Christ.
That is exactly what Jesus encourages us to experience. First, that we live so close to him that we can’t help but be confronted by people reviling us and seeking to attack us because of our faith in Christ. Second, the attacks and claims of evil against us must be false – i.e. we must not we living in falsehood or evil. The blessing (happiness in the Lord) that takes place here is in our looking to Jesus as both our Savior (who saved us and keeps us safe in Him) and our Lord (who we trust and obey). The eyes on Jesus are going to be blessed eyes, they are going to be attached to a body that seeks to serve Christ in spirit and in truth, and who, by looking to Jesus, avoids the evil pitfalls that are gathered all around. Be happy – look to and trust in Jesus and expect to enjoy some attacks along the way. The battle is not ours, the battle belongs to Jesus and he has already won. Amen.
