I think the first question we can as ourselves is why the Holy Spirit led Jesus into the wilderness?
I don't know if I can give the answer to the question, but I think we can learn something from the fact that the Spirit did. It shows that even being perfect here on earth, as God is perfect, does not mean that we do not have temptations or difficulties. Last Wednesday I wrote a small bit about the growing in virtue, and this Gospel passage shows that it is normal to have to work on ones dispositions in life, even if we could be as perfect as God.
The three temptations which the Devil brought forward, can be seen as very ordinary in ones life, and I will try in this reflection to highlight some small aspects of that and to give some material for further reflection.
In the first temptation the Devil simple challenges Jesus: "If you are the Son of God, command this stone to become bread" (Luk 4:3 RSV) as "he ate nothing in those days; and when they were ended, he was hungry" (Luk 4:2 RSV). So why did Jesus not just do that? I think is because He was in the desert for a reason, maybe to prepare himself in prayer for His active life, maybe some other reason, but there was one. Just breaking it off because He was hungry wouldn't fulfil it, but would be taking the easy way out, a break at the last moment, exactly the devil wanted, especially as it in now at the end, just before "the angels ministered to him" (Mar 1:13 RSV)
In the final temptation, where Jesus is standing on the pinnacle of the temple and the devil challenges Him:"If you are the Son of God, throw yourself down from here" (Luk 4:9 RSV) we read that the Devil can quote scripture too: "for it is written, `He will give his angels charge of you, to guard you'" (Luk 4:10 RSV). I think this is the most challanging one for me in a way. The temptation in this situation, especially after for example being hungry and tired after the forty day period in the desert possibly while experiencing an absence of God, would be to ask for a sign. To throw yourself off the temple, wanting God to save you, forcing Him to make a move. Although maybe a bit of a cliché, in a way it is a lack of trust in God. This temptation I think I would often experience, when I ask myself why God does not act, why I don't experience Him as I did before, why he does not do something (which I think he should do). But instead we should take Jesus again as an example, "It is said, `You shall not tempt the Lord your God'" (Luk 4:12 RSV): we have to trust in God!
Finally, "And when the devil had ended every temptation, he departed from him until an opportune time" (Luk 4:13 RSV) It just want to close with this quote, as again it shows that we should never expect to reach a state in which we have 'conquered' the devil, in this life there will always be a return. But we can grow in virtue, we can grow closer to God, we can enjoy life to the full, and we can use the temptations in a way to archive this as with Jesus as an example and as the goal.
