Reconciled through the Atonement

I was thinking about this concept regarding eternal marriage, and comparing it to marriage not sealed by the Priesthood for eternity. In normal marriage, it's not a triangle with binding promises and covenants between each member, it's just a line between two people and they can move further or closer to each other. Unfortunately those promises made between just the two people are sometimes taken lightly and broken, and the whole marriage is thrown away without much thought or effort. So often we see marriages falling apart, and I've noticed it a lot in celebrity news. A common reason given for divorce is "Irreconcilable differences", which always kinda confused me. What was it that they couldn't reconcile? Why couldn't they reconcile? If only there was a way to become reconciled, right?

Reconcile means to bring into agreement or harmony, make compatible or consistent, to re-consecrate, to restore, to make good again, to repair.
The way I usually think of the word "reconcile" is being reconciled to God through the Atonement of Jesus Christ. When you consider those definitions with the Atonement in mind, it makes so much sense!

Our purpose in coming to earth is to learn and progress. We all wanted that opportunity, but coming here came with a price. We would be separated from God, our Father in Heaven. We're separated not only by distance, but by death and sin. These are obstacles that we couldn't overcome. Basically, death and sin are our "irreconcilable differences" between us and God. We needed a way to be reconciled to Him, to repair the breach between us. It's a gap we couldn't fix ourselves, we needed someone to do it for us- to be a mediator.
Thus, the only way for us to be reconciled to our Father in Heaven was through the help of our elder brother, Jesus Christ. He could be the mediator for us because death and sin had no hold on Him. He came to earth just like us, but unlike us He lived a sinless life, giving Him the power to overcome the obstacle of sin and pay the price for us. Jesus Christ is the line that connects us to Heavenly Father, that repaired the gap between us. We are reconciled to God through the Atonement of our Savior Jesus Christ. I am so grateful for this!
It takes effort on our part too, just as any other relationship works. But we don't have to let the irreconcilable differences of mortal life keep us away from our heavenly home and our heavenly parents forever.
I'm also grateful for the gift of eternal marriage and eternal families! It's comforting to know that the things that matter the most will last forever.
