Matthew 5:18

For I assure you and most solemnly say to you, until heaven and earth pass away, not the smallest letter or stroke (of the pen) will pass from the Law until all things (which it foreshadows) are accomplished.  

God is our leader in this life and has a plan and promises to fulfill from His covenant with the Jews. The Bible shows us who God is and why we can trust in this plan even if the world is spiraling into sin. Our job is to keep our eyes on God and the word, not the world. We must trust the leadership of God and the plan.
