Grab a cup of coffee and sit down to read the whole book of I John today if you have a minute. If the negative feels more real than the positive; then you need this reading. If your brother is frustrating you; then you should find the solution right here. If you have been muddling in discontentment and griping, and you are tired of it; you can change that today.
Abide in the Son. Love your brother. Walk in Light. It is funny (scary and dangerous) how we so often think that while we ferret out the errors in another, we believe we are being discerning even though we are doing anything but agape-ing him in the process. It is the worst kind of blindness.
