My belief is that as Christians we are to spread the word to non-believers. People who are not raised with Christ must be taught about the good news in order to understand it. None of us would be Christians today if those that taught our ancestors didn't believe that. Paul says about marriage:
"For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her husband. Otherwise your children would be unclean, as it is, they are Holy." 1 Corinthians 7:14
We also know this:
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices in the truth. It always protects, always trusts, always hopes, always perserves." 1 Corinthians 13:4, 5, 6
I feel that if you love each other, he is a good man, and you love the Lord with all your heart, you could be the vessel of his deliverance. Remember, Jesus is our model in life. The goal of all Christians put very simply is, be like Christ.
"While Jesus was having dinner at Matthew's house many tax collectors and sinners came and ate with him and his disciples. When the Pharisees saw this they asked his disciples, "why does your teacher eat with tax collectors and sinners?" On hearing this, Jesus said, "It is not the healthy who need a doctor but the sick." Matthew 9:10, 11, 12
The most important thing for you should be your faith. If that foundation is solid in the Lord I do not believe you can be yoked.
God bless,
Chris
