Some food for thought
No political slogan or hand-held sign has ever changed someone's convictions. Protests, shouting, and political battle will only polarize people on an issue. Regardless of which side wins or loses a political struggle, people will continue to believe what they did before. If you want to change your community, your nation and your world, the most effective action you can take is to introduce people to Jesus, and to demonstrate His love and compassion to them. Through His death and resurrection, all of us can be free from the effects of sin, and enjoy unlimited and joyful relationship with God. This is where changed lives come from.
It is a good thing to participate in politics as God leads. Vote your conscience. Respectfully voice your convictions in the political arena. But don't expect the election of a politician or passage of a law to change people's minds and hearts, much less their lives. Political power and law rule only through fear of consequence, not love. Let's make our focus the same as Jesus'. People are transformed when they experience love in relationship with Him.
