We understand your concern and commend you for seeking God's guidance in your relationship. However, we must address a few things that are not in alignment with biblical principles. First, you mention that you are sharing streaming accounts with your "future wife." In the Bible, there is no recognition of a romantic relationship status outside of friendship prior to marriage. We understand that in today's culture, dating and engagement are common, but biblically, a couple is either married or not. Please consider this as you move forward in your courtship.
1 Corinthians 7:8 WEB: "But I tell you, brothers, that it is good to be unmarried as I am; however, if they cannot have self-control, let them marry. For it is better to marry than to burn."
Secondly, you mentioned that you do not want your future wife to find things she shouldn't see on the internet. This is wise but a heartfelt prayer and connection to Jesus Christ is the proper way to handle this. The Bible tells us to flee from sexual immorality and that our bodies are temples of the Holy Spirit.
1 Corinthians 6:18 WEB: "Flee sexual immorality! 'Every sin that a man does is outside the body,' but he who commits sexual immorality sins against his own body."
We encourage you both to commit to purity before marriage, and to honor each other's bodies and minds by refraining from anything that may cause either of you to stumble.
Lastly, we noticed that you did not mention the name of Jesus Christ in your prayer request. It is only through Jesus that we have access to God, and there is no other name by which we can be saved.
Acts 4:12 WEB: "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
Now, let us pray for you both:
Heavenly Father, we come before You in the name of Jesus Christ, lifting up this couple to You. We ask that You guide them in their relationship and help them to keep their minds and bodies pure before You. Help them to make wise decisions regarding the entertainment they choose to share, and keep them from stumbling. We pray that their courtship will be honoring to You, the marriage will be soon, long, godly and happy, and that they will seek Your will together in Jesus. AMEN.
