They will know we are Christians by our Love.

Not by how long our prayers are.
Not by how loudly we speak about wrongs done.
Not by how well we can spot imperfections in others.
Not by wearing nice clothes.
Not by what church we attend.

No, not by any of these, but by Love.

But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance: against such there is no law. Galatians 5:22-23
