This is what happened when the Jews plotted the crucifixion of Jesus in our text verses. It is important to remember that God can, and often does, use a bad decision in a way we never expected. For example, in 1963 my daddy bought a 1958 Edsel. This was, at the time, considered a bad decision. But in 1963 it was a bad decision.
Decisions are a part of life.
You make them every single day. You decide what you are going to wear. You decide which road you are going to take to church, to work, or to school. You decide which automobile you are going to drive, if you have more than one. You decide how to spend your money.
