Joab had defected to Adonijah, though he had not defected to Absalom

1 Kings 2:28
Joab had defected to Adonijah, though he had not defected to Absalom.

This can be used as a lesson for temptation, which are usually a short time frame between the decision to sin. However, the decision to defect may have taken a long time for Joab to decide. He chose to be loyal to King David at one time, but later he switched to Adonijah. Even a well-thought out decision can sometimes be the wrong or unrighteous one, even though it seemed the right thing at the time. Having made a right decision, whether it is an important decision or not, does not always guarantee that we will know how to make the right decision in the future, though it may be a smaller decision. All the more we cannot be complacent about what we stand for and who we are.
