God wants all people to be saved. When we say "all," it means that no person is exempted from God's saving grace – all people from all walks of life, all cultures, all nations, all ages and all personalities are in God's heart. He wants all of us Christ followers to have this same heart, and He wants all of us to demonstrate this at home, too.
The Bible gives us accounts of God showing His saving power in Christ to whole households. The book of Acts alone gives us several examples.
In Acts 10, we read how God brought the gospel to the home of Cornelius, a Roman officer. He, along with his relatives and some close friends, were able to hear the gospel of Christ and become baptised in the Holy Spirit. Think about it: Cornelius' household, and some of his friends, all became part of the family of believers in one fell swoop!
In Acts 16:29-34, we also find a wonderful account of how God saved the family of a jailer guarding Paul and Silas, all in the middle of the night!
"The jailer called for lights and ran to the dungeon and fell down trembling before Paul and Silas. Then he brought them out and asked, 'Sirs, what must I do to be saved?' They replied, 'Believe in the Lord Jesus and you will be saved, along with everyone in your household.'
"And they shared the word of the Lord with him and with all who lived in his household. Even at that hour of the night, the jailer cared for them and washed their wounds. Then he and everyone in his household were immediately baptised. He brought them into his house and set a meal before them, and he and his entire household rejoiced because they all believed in God."
God loves you and your family
Based on those accounts alone, we can see that God is not content to save you – He also wants to save your family, including your spouse (if you're married), your parents, your siblings, your cousins, and all your relatives. God loves all of them, and this is why you should also share the gospel with them!
If we are truly saved, our desire to bring the gospel to our family would be unstoppable. If we love our families, then we should share the life-saving truth of the gospel of Christ, no matter how hard or how long it takes.
"Peter replied, 'Each of you must repent of your sins and turn to God, and be baptised in the name of Jesus Christ for the forgiveness of your sins. Then you will receive the gift of the Holy Spirit. This promise is to you, to your children, and to those far away—all who have been called by the Lord our God.'" (Acts 2:38-39)
