I encourage you to read Romans (particularly chp 4, the beginning of 5, and chp 8). I did so the other day, and it brought such inexpressible abounding hope, that I became misty eyed. To read stories of the ones who walked in faith before us, and see ourselves living in the same way is incredible! Abraham and Sarah are quickly becoming my favorite people in the bible. As I was reading Romans 4, verses 20-21 jumped out at me. They are a powerful poignant reminder of God's promises to myself, to John, and to the world around me:
Too often we don't give God enough credit. God is God; He is the ultimate supreme King of Kings and Lord of Lords. Compared to Him, we are nothing. We truly are. He created us, and He knows what our lives shall be like from this day forward. If we cling to Him, and those shadows of hope that linger during the hard times, we shall emerge victorious!
Two more verses I'd encourage you to look up are, Romans 8:37, and Romans 16:20. Romans 8:37 is my favorite verse. In fact, I wear it on a necklace quite often to remind myself that God knows what's going on, and I need only to trust Him. Romans 16:20 made me misty-eyed again when I finished reading through Romans. To see God's sovereignty over all is a humbling thing. To know He intercedes for us, is another.
