The third letter Apostle John wrote was to a dear friend, Gaius. John praised his friend for walking in the truth and love of Jesus Christ with hospitality for other church members.
If Christians really knew the truth and love of Jesus Christ, they would act nice. All Christians are called to stand apart from the world with their patience, joy, peace, love, self-control and kindness.
Unfortunately, most of us do not. But help for spiritual growth is only a prayer away!
