Proverbs 1:28 (NIV) Then they will call to me but I will not answer; they will look for me but will not find me.
1 Corinthians 16:9 (NIV) because a great door for effective work has opened to me, and there are many who oppose me.
When one door closes, another opens, but we often look so long and regretfully at the closed door that we do not see the one that has opened for us. —Alexander Graham Bell
