The Bible has a lot to say about families, it even mentions the ideal family.
Finally, all of you, be like-minded, be sympathetic, love one another, be compassionate and humble. (1 Peter 3:8)
This seems simple, but a lot of families have issues. Even the most close families will have times where they find themselves having issues they must overcome. And the Bible is full of stories where families are challenged with issues. Genesis 3 is the first known case in the Bible where both the husband and the wife disobey God, only later to have one of their children kill another one of their children (Genesis 4:8).
A person’s family can challenge them in every way. Yet we cannot just simply abandon, or give up when times are hard. A family needs to learn to stick together, and meet the challenge, working together to get through the issue.
2 Consider it pure joy, my brothers and sisters,[a] whenever you face trials of many kinds, 3 because you know that the testing of your faith produces perseverance. 4 Let perseverance finish its work so that you may be mature and complete, not lacking anything (James 1:2-4).
12 Blessed is the one who perseveres under trial because, having stood the test, that person will receive the crown of life that the Lord has promised to those who love him (James 1:12)
Even when we have lots of issues with a family member we cannot just abandon them, or stop taking care of them. The Bible does not have anything good to say about such a person who does.
8 Anyone who does not provide for their relatives, and especially for their own household, has denied the faith and is worse than an unbeliever (1 Timothy 5:8).
True, it is not always easy. If you have a child who has become addicted to drugs, and takes money out of his own mother’s purse. It can be hard to trust that child. And yes… Sometimes denying that child something, you are helping him.
However, if he is hungry, you still must feed him/her. If they are sad you must still be there for them. Ultimately you are trying to build them up in the Lord (Romans 15:1) when you do this. And if you trust God, he can make your family stronger and better (Isaiah 40:31).
You must also be ready to forgive that family member when they have turned from their sin. Remember what it says in Matthew 6:14 – 14 “For if you forgive other people when they sin against you, your heavenly Father will also forgive you.”
Trust God. Let him guide you. Live as God wants you to live.
22 Do not merely listen to the word, and so deceive yourselves. Do what it says. 23 Anyone who listens to the word but does not do what it says is like someone who looks at his face in a mirror 24 and, after looking at himself, goes away and immediately forgets what he looks like. 25 But whoever looks intently into the perfect law that gives freedom, and continues in it—not forgetting what they have heard, but doing it—they will be blessed in what they do (James 1:22-25)
And remember, you are not the first or only dysfunctional family. And God will not abandon you. You however must be willing to trust God in all things.
