Well to be honest there is not much to discuss. I have never had either. Both are something that I treasure and am not going to give away lightly.
Proverbs 4:23 says this...
"Guard your heart more than anything else, because the source of your life flows from it."
This verse has always rang true in my heart. It is one of my favorite verses and it shows the importance God places on our hearts. They should not be taken out and given to just anyone. They are to be treasured and kept safe. Once you put your heart out, you have to be willing for that person to do with it what they want. So it is only makes sense that your heart would only go to those that you know will treat it with care. Those that God say to share yourself with. This is not only applicable in romantic relationships but any relationship that you have. Even in sharing the word of God with someone. We have to seek God and listen to his promptings before we share things.
Love is such a beautiful thing, if it first comes from God. He is the only source of real love, everlasting and unchanging.
