In Hebrews 13 we are taught to greet strangers kindly and even to bring them into our homes, because we never know when it might be someone sent to us from God.
Those that are "in bonds" should be remembered consistently, as if we were there with them. Those around us who suffer should be cared for as if it were ourselves who were experiencing the suffering, and we should have compassion accordingly.
Marriage is considered an honorable thing, to be treated as extremely sacred. Anyone who breaks those sacred bonds or hurts a family by their actions will be judged of God.
We should be content with the things we have been given, because God will be there for us and provide for us. Coveting isn't worthwhile because they aren't things we even need, so why waste the energy?
Christ is the same yesterday, today, and forever. He will never go back on his word, or fail to love us. We are sanctified by his blood, and by his sacrifice for us.
We should submit humbly to those who are given the ability to rule over us. However, if those who are ruling us do not follow the teachings of God, we should uphold God's law in all things before any laws of mortal men.
Paul asked us to pray for the leaders of the church in their journeys, and we should keep this in mind even today. We should pray for these men and women who lead the church and have dominion over us to protect us because they are our first line of defense.
