I repeat your spot on question. What are Christians going to do about this attack on their existence? The power of prayer should also give them the strength to fight the attack rather then just turn a cheek and warm a pew.
The gays will say that the Church discriminates against them. They are playing the same game as those who wanted racial equality. The cause of racial equality is a noble one. All humans are part of Gods creation. However, behavior that defines who you are is based upon choice and not all choice is equal. The purpose of the attack on the Church is the effort to destroy the Church which is the last bastion against government control of the individual.
The Marxists are destroying America from within. Same sex marriage is one more tactic from the Marxist tool box. It has become ingrained into the mindset of the Left to use their freedom of speech to indoctrinate their fellow citizens to what they want them to believe and limit the freedom of speech that says otherwise. The freedoms enjoyed by generations of Americans have degenerated into a tyranny that scorns Americas legacy of freedom to pave the way for the political oppression of the individual. This collective social model that opposes our Constitutional heritage is the way of the Marxist. Homo marriage has deeper implications than you can imagine. It is designed to control the individual by separating him from the sovereignty of the family. Pretty soon, when all the widgets that hold together our society have been loosened, the critical mass will have been reached and we will explode into the universe of history. Human beings will once again be set back in time to when the individual was the slave of the state.
Also a time for greater witnessing for the Gospel of Jesus.
