Did you ever consider when God sends trials and tribulations your way, that He considers you faithful enough to go through them? Job was chosen by God to go through what he did because he was faithful. In Luke 1:26-38, we see where the Angel came to Mary to tell her "Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women." Mary had "found favour with God." He considered her faithful and chose her to bare His Son.
Think about what Mary went through in those days. She was engaged to Joseph, then she turned up pregnant. Imagine how everyone talked about her and shunned her. And what about Joseph?! Here he is engaged to this woman and now she's pregnant. (Unfortunately these days, this is not uncommon. But, in those days it could have been fatal.) We later see that an angel came to Joseph in a dream, Matthew 1:20-25, and told him what was really going on. Then he married her, but didn't "know" her until after the baby was born.
God considered Mary faithful enough to endure the hardships of having and raising His Son, AND enduring His crucifixion. Sit and ponder ALL that entailed. For me, it makes me feel very humble at what He considers me faithful enough to endure - and ashamed at all the times I've complained.
