"But if anyone does not provide for his own, and especially for those of his household, he has denied the faith and is worse than an unbeliever." 1 Timothy 5:8 (NAS)
With no end of needs in your community and beyond, how do you know where to start trying to meet them?
You start at home. Your family needs you to set the example of being the hands and feet of Jesus to others, including them. Take care of yourself--body, mind, and spirit--so you can take care of your family's physical, emotional, and spiritual needs. Then work with your family, not independently of them, to meet needs in your church, job, extended family, neighborhood, and social circle as you are able.
If you're habitually being short with your household members because you're preoccupied with taking care of business, it's time for a priority evaluation. If you're not sure how you're doing, pray, then ask the people you live with, and humbly consider their responses.
"So, as those who have been chosen of God, holy and beloved, put on a heart of compassion, kindness, humility, gentleness and patience; bearing with one another, and forgiving each other, who ever has a complaint against anyone; just as the Lord forgave you, so also should you." Colossians 3:12-13 (NAS)
Let God's peace and provision set the atmosphere in your home, and let His love radiate outward from there.
