And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her. Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear? Genesis 17: 16, 17
But Sarah had faith:
Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised. Hebrews 11:11
Because their faith had been given opportunity to grow through their trials, Abraham and Sarah were prepared to prove their willingness to the Lord and sacrifice their son. They followed the Father's will in faith. Abraham made it as far as having Issac on the alter before the Lord stopped him.
I don't think I have ever felt as much faith in my life as I did the day my husband died. I can imagine a small piece of what Abraham felt. Except, I knew how the story of Abraham and Issac ended. I knew the Lord just wanted to test him - and then his son would return to him.
As I stood in the hospital room when my husband lay on the verge of this life and the next, I was willing. I was willing to give him to my Father in Heaven. I was willing to let go. But I would be lieing if I said I didn't wish. Wish that this was my test. That I had to be pushed this far. That he was before me about to cross to the other side - and I just need to prove to the Lord that I would believe Him... even unto death. That I would trust in Him. And then once I did, my husband would be healed. And much like Abraham and Isaac walked back down off that mountain, my husband and I could walk out of that hospital.
I guess the difference was that for me, this was just the beginning. For Abraham and Sarah, this was closer to the end of their trials that would prove them qualified for the promised blessings.
