Fortunately for those of us who are Christians, the only witness to our Christianity that is necessary is Christ, Himself. The only One He will witness to, is the one and only Father God.
Unfortunately, we Christians have a long history of dividing ourselves. Read Acts, Romans, Galations, Corinthians, etc. Our job is to try to be one with one another, so that the world will see that we are one with Him and that He is One with the Father. None of us is perfect, yet.
God bless you for giving me the opportunity to witness.
You are welcome.
My intent too, is to end this petty squabbling among ourselves. We may not agree on religion but I think we can come together in politics and put aside our religious differences to work for the common good.
