Jesus was tempted in the wilderness where He was tired, alone and hungry, and thus most vulnerable.
The devil often tempts us when we are under physical or emotional stress. When we are lonely, tired, weighing big decisions, or faced with uncertainty is prime time for assault.
He also likes to tempt us through our strengths when we are most susceptible to pride. We must be on guard at all times against his attacks. Being tempted is not sin. Succumbing to temptation is sin.
The devil’s temptations focus on three crucial areas:
Physical needs and desires
Possessions and power
We may also be tempted to satisfy a perfectly normal desire in a wrong way or at the wrong time. Many of our desires are normal and good but God wants us to satisfy them in the right way and at the right time. If we are going to resist temptation, knowing and quoting Scripture is a very powerful tool against the tempter.
Because Jesus faced temptations and overcame them He can assist us in two important ways; as an example of how to face temptation without sinning, and as a helper who knows what we need because He went through the same experience.
