Proverbs 18:22
and Matthew 22:30.
Marriage is a good thing, and God withholds marriage in eternity.
I wouldn't say Jeremiah is my role model, i think you brought him up first, but it is a good case potentially to look at, where God withheld marriage from Jeremiah, and it seems to not really even touch on whether or not Jeremiah wanted to have his own family or not. If God forbid it on this earth, and Jeremiah wanted a wife and children, all we know in how God "makes good" on that commitment to be a "eunuch for the kingdom of heaven" is Isaiah 56:3-6
3 Neither let the son of the stranger, that hath joined himself to the Lord, speak, saying, The Lord hath utterly separated me from his people: neither let the eunuch say, Behold, I am a dry tree.
4 For thus saith the Lord unto the eunuchs that keep my sabbaths, and choose the things that please me, and take hold of my covenant;
5 Even unto them will I give in mine house and within my walls a place and a name better than of sons and of daughters: I will give them an everlasting name, that shall not be cut off.
Sure, in eternity you won't need children to carry on your family name, so the promise of a name that will never die can be better in that sense that you don't have to look to children to continue your name and inheritance.
But as far as for having children just to love them and raise them and teach them and see them grow into godly people, and see them have their own children? A name is no replacement for that.
I don't know if Jeremiah had those desires or not, maybe the Lord simply never gave him those desires to begin with.
But for me, I do have them, and frankly, recommitting my life to Jesus made me more aware of them, not less.
In my late teens and early 20's when i backslid. I didn't think about marriage, and I thought I didn't want children, too much of a hindrance on lifestyle, and marriage? Nah just a desire for sex. Going back to Jesus.. changed a desire for just physical lust and sex, into a desire for love and intimacy with just one woman, because that is what the Lord designed, and it seemed way more beautiful of a concept than I had seen it as before, and made me desire children, even though I know genetically that'd be a very bad idea for me to have.
But this one verse.. shatters everything. Any negative feelings I have towards the Lord, come from this one verse (well and it's parallel in Luke)
