The most important thing  for you to know is that God loves each member of your family so much that he has already made the way for your family to come to know him and receive his free gift of everlasting life, through Jesus Christ. (John 3:16, Ephesians 2:8, John 17:3).

 

The bible clearly tells us that, it is by the grace of God you have been saved, through faith, nothing to do with self effort or good works. Therefore the same applies for your unsaved family members. It is God's free gift to anyone who will believe in the Lord Jesus Christ and be saved. From that basis you rise up and exercise your God given Faith (Hebrews 11:6) and clear the way in prayer, through the word of God on behalf of your loved ones. You are God's ambassador in your home and it is time NOW, for salvation (2 Corinthians 6:2).
