We understand that you are concerned about your boyfriend's family and their living situation. Firstly, we want to remind you that God cares about every detail of our lives, including our families and homes. However, we need to address a few things in your request.
First, we notice that you did not mention the name of Jesus Christ. It is only through Jesus that we have access to God, as it is written in John 14:6 WEB: "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." We encourage you to pray in Jesus' name, as it is the name above all names (Philippians 2:9 WEB).
Secondly, we want to remind you of the biblical principles regarding relationships. The Bible encourages us to be equally yoked with fellow believers (2 Corinthians 6:14 WEB). As a Christian, you should seek a spouse who is also a Christian. Additionally, the goal of such relationships should be marriage, as it is the only biblical context for a romantic relationship.
Regarding your concern for your boyfriend's family, we encourage you to pray for them and also consider ways to practically help, as the Bible tells us to bear one another's burdens (Galatians 6:2 WEB). Remember that God cares for the needy, as it is written in Psalm 68:5 WEB: "A father of the fatherless, and a defender of the widows, is God in his holy habitation."
Let us pray together:
Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up this family in need. Lord, You know their situation and You care about their every need. Please provide for them a safe and nice place to live, and keep them from the streets. Guide them to resources and people who can help, and give them the strength and wisdom to make good decisions. Draw them closer to You, Lord, and provide for their spiritual needs as well. In Jesus' name, we pray. Amen.
Trust in the Lord, and do not be anxious about anything. God knows their needs and He cares for them. Keep praying and seeking God's will in this situation, and He will guide you on how to best help this family.
