Already dating an unbeliever
If you are a believer and you are already married to someone who is an unbeliever, God's Word tells you to stay married to your spouse (see 1 Cor. If on the other hand, you are a single Christian who is considering getting married to an unbeliever, don't do it.
Are there many marriages where the couple is unequally yoked? By allowing your heart to be given to an unbeliever, you risk placing yourself in a situation where it may be very difficult to walk away. As a believer, do you really want to marry someone who will not be in a position to rely upon the love of God when you do things wrong and need forgiveness?That's not to say that every Christian couple always relies upon God's love to forgive one another, but at least in that situation it is available for those who are wise enough to receive it and share it with one another.All an unbeliever has to draw on is "human love," and that is incredibly weak when compared to God's love. Or would you rather have a marriage that soars higher and higher through the supernatural love and power of Almighty God? But there is an enormous difference between a marriage of two believers, and a marriage where such unity is nonexistent. We must first receive God's love in Christ before we can start to love God. Even though we have all made many poor decisions in life, our Lord is big enough to meet us where we are at and help us to love Him as we go forward in Christ.Your marriage certainly won't be perfect no matter who you marry. So if you are still single, don't settle for someone who rejects the very Savior who shed His blood on the cross for your sins. We must first be converted in order to be brought into God's family. (see Hebrews11:6)You may find yourself today in a challenging situation as it relates to these issues. Here is one final word to every married man who wants to do God's will: "Husbands, love your wives, just as Christ loved the church and gave Himself up for her." (Ephesians ) Marriage requires sacrifice. And marriage without Christ is not marriage as God designed it.There is no spiritual unity between a believer and an unbeliever. The new birth results in a new life and a new spirituality.
There is no unity on that level unless both people are converted through faith in Christ.
That only happens when both of them are in a relationship with God.
Then and only then do they experience sex as God intended.
While their souls and their sexual relationship will not share any spiritual depth, the couple will nevertheless be loved by God.
And hopefully the unbeliever will be won over by the witness of the Christian spouse and the working of the Holy Spirit.
Without the first thing being in place, the sexual intimacy will not be the ultimate expression of God's design.
