Plus, when you throw in children, and how to raise them, it becomes even worse. Also, keep in mind that once you ARE married, divorce is not an option.
A believer is not to leave an unbeliever (although an unbeliever can leave) (1 Cor -16). Anything that might come ahead of God we are to avoid. if a person is a non-Christian, God is obviously not first in his/her life, right?
(Also see: Eph 5:6-8,11) Several things can be taken from this: we (Christians) are declared "righteous" and unbelievers "unrighteous." Christians are "light," and unbelievers are "darkness." Christian's bodies are the "temple" of God, unbelievers bodies are not.
Unbelievers are called "infidels" and "unclean." This concept of being "unequally yoked" goes back to the Old Testament.
for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
And, in the end, isn't your evangelism ultimately self-serving rather than selfless?Let me close with one more BIG point for you to consider. " A good definition of idolatry is: For the Christian, God is (or should be) first. This being the case, doesn't that make EVERYTHING in the non-Christian's life an idol? Do you really want to enter into a relationship with an idolater?There are a number of examples in the Bible of God's people entering into a relationship with idolaters and it going badly. (1 Kin 11:1-10) talks about how Solomon had married many pagan (unbelieving) wives, and as a result, "when Solomon was old, his wives turned his heart away after other gods; and his heart was not wholly devoted to the Lord his God..." (1 Kin 11:4)(Also see: Neh -27).This was for their protection, so that they would not fall into sin and turn from living totally for God.I believe it very wise to follow these warnings as well today.
