"For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts." -Isaiah 55:9, KJV
"Man's goings are of the LORD; how can a man then understand his own way?" -Proverbs 20:24, KJV
"And we know that all things work together for good to them that love God, to them who are the called according to his purpose." -Romans 8:28, KJV

Even as things happen in our lives that we cannot figure out, God is still in control. God's ways and thoughts are so much above ours that we cannot hope to fully understand them in this life. As He is also in control of our lives,  we will experience many things that we do not understand. God has a plan for us, and He is always working to fulfill that plan--even when it doesn't look like it.
