Like a medical test that comes back with inconclusive results, what do you do when the evidence you know God is inconclusive? Look for 3 signs: 1) we keep God's commands, 2) we love each other, 3) we have God's blessings. This is not a looking in to rely on ourselves - as that would leave us overly-worried (with such a shaky foundation) or overly-confident (when we have no reason to be). Instead the signs point upwards - we keep God's commands because God's at work in us; we love God's people because we're in the light; and we have God's blessings because we have Jesus who brings them.
