Proving Your Faith in Christ - J.C. Ryle

I charge you never to neglect the duty of brotherly love, and practical, active, sympathetic kindness towards every one around you, whether high or low, or rich or poor. Try daily to do some good upon earth, and to leave the world a better world than it was when you were born. If you are really a child of God, strive to be like Christ in heaven. For Christ's sake, do not be content to have Christianity for yourself alone. Love, charity, kindness, and sympathy are the truest proofs that we are real members of Christ, genuine children of God, and rightful heirs of the kingdom of heaven.
