Love is a packaged deal.
When you marry someone you can't marry them just for their body, or just for their looks, or sense of humor. You marry them for everything. Good days and bad days. Laughter and anger. Sweet things and bitter things.
You love their body and soul.
Jesus gave us an example to follow when He died for us. He died not because we were good, but because we were not. "But God demonstrates His own love for us in this: While we were yet sinners, Christ died for us."
'While we were yet sinners.' Not 'once we were good enough' or 'when we were ready' or 'once we could cope on our own', No, 'while we were yet sinners.' Christ loved us and still loves us for our good and bad days, laughter and anger, sweet things and bitter things. He loves and cares for us despite all of our flaws. Despite the fact that we will never be able to repay Him for all the things He has done for us.
And so, just as He accepts that about us, we need to respect our spouses. Flaws and superiorities.
