I don't get it. But then again when she/they started throwing bible verses in there I stopped reading it for real.
This is funny -
4. Set boundaries during courting and the engagement period to ensure your king is presenting you holy or your queen is presented holy.
And so I guess the author/s do think it's hard/impossible to be with one person all his/her life according to this lol -
6. Stop thinking that being married to one person for the rest of your life is impossible. Start living your life according to Godís plan and not your own. Because when we live it according to us and other humans we fail, but all things are possible with Him.
