Nothing blesses a person’s life more than a decision. Prayer won’t even be necessary, because the decision turns into a blessing.
This is what happened with Abraham. The order was given: "Leave everything behind and go to an unknown place”. He could have stayed, but he made a decision that turned him into the father of a great nation.
Jonah, who also received an order, did the opposite. He also made a decision, but his outcome turned into a curse: he ended up in the belly of a big fish.
