When Jesus was baptized, God his Father spoke to the crowd out of thin air and the Holy Spirit descended on him like a dove and rested on him. This was his moment of commissioning: he could have capitalized on that and started gathering crowds to himself. So what he decided to do instead was go into the wilderness for over a month, by himself apart from a few lizards and various other wild animals. Why would anyone do that? If God spoke in an audible voice to the crowd in my local town, saying that I was amazingly special to him, while a dove came down from Heaven and perched on my head, I think that I would want to make something of it. "If you want to know more, then come along to church this evening at 7.30 and I'll explain what's going on!" Perhaps I'd find a friend to set up the stage and get the PA working, contact a worship leader to provide some music at the start of the meeting, change into my best clothes and write some notes for the talk of a lifetime - not go away for a month until everyone had forgotten!
Ash Wednesday is, as you are probably aware, the first day of Lent, when we remember that Jesus was in the wilderness for 40 days and nights. We sometimes give up something during that period to help us focus on prayer; Jesus gave up food, altogether. It's easy to get the impression that he fasted for 40 days, then the devil said three things to him and it was all over. However, Luke makes it clear that he was tempted throughout that period, which is also implied by Matthew. This was Jesus' first month or so of the rest of his life - the first 40 days of his mission. He needed to get some things straight, lay the ground rules for himself. He went to the wilderness with the Holy Spirit and presumably spent quite a bit of the time with his Father as well. But this was also the devil's moment to wreck the whole plan. If he could put Jesus off course, or even stop him altogether, then Jesus' victory over him on the cross wouldn't happen. The devil might not have known all the details, but the day the Messiah received his commission was going to be a worrying time for him.
So those 40 days were a struggle throughout. Jesus chose to fast, presumably to make himself more spiritually aware so that he could tune in properly to the Father and Spirit. It also made him more susceptible to spiritual attack as well. It seems that the 40 days went OK for Jesus. Whatever the devil threw at him hadn't caused a problem. By the end, Jesus was probably extremely weak, but also very open to the spiritual realm in a way that his human body possibly didn't normally allow in quite the same way. At that point his enemy struck at the core of his mission. We shall look at those temptations in later posts, but suffice it to say that Jesus came out of the time without having given any ground at all to his tempter. The ground rules were in place: Rule One was not to pay any attention to those voices that would cause him to stumble.
Temptation comes in many forms. The Screwtape Letters are a light-hearted but deadly serious attempt by C S Lewis to make this point. We can be tempted to do things that we know we shouldn't. We can start to think that we're not up to much and certainly not useful to God. We might even find ourselves beginning to doubt the very existence of God. Don't listen to these thoughts. Don't give them the time of day. Hold on to the truth in question and declare it back to yourself. Tell the negative thoughts to go away; you can use the name of Jesus to do that. Go back to what you believe and remind yourself why you believe it.
This is a war - a war to get you off course, just like Jesus was tempted to go off course. You need to establish your ground rules, not the devil or whatever of his minions he might send to try to persuade you otherwise. One of those rules, like in Jesus' case, needs to be not to pay any attention to the voices that would cause you to stumble.
