The burning of Qur'ans is totally against what Jesus taught. A church has no business engaging in it. Jesus said we are to love our enemies. What would Jesus do?: speak the truth in love and show that love to Muslims even if they are aggressive and unreceptive. "While we were yet sinners, Christ died for us."
"Herein is love, not that we loved God but that He loved us and sent His Son to be the propitiation for our sins. Beloved, if God so loved us, we ought also to love one another." 1st John 4:10-11
Also, remember the parable of the servant who was forgiven by his master of a very great debt but then went out and had a fellow servant put in jail for a small infraction. When the master heard about the incident, he was furious because he had forgiven much.
Our job as Christians is to love, forgive and pray for Muslims. It is our government's responsibility to uphold the laws that our Constitutionis based on.
