One danger we face after we have come to know the doctrine of
unmerited favour from God and His unlimited love and mercy is that we
slowly allow ourselves to lower our guard against sin. Satan helps us
in this direction by warning us (as if he is an angel of light) that
we shouldn't be legalistic about the commandments of God. But when we
are not "watching and praying lest we should fall into temptation" (Mt.
26:41) we fall! Temptation comes unexpectedly and in subtle ways, and
we are caught off guard. We may fall not only because of this, but
this is one of the main reasons why we fall, and one that Jesus has
specially warned us about.
A well known military saying is, "In times of peace, prepare for war."
Times of peace are when training gets done, equipments are bought or
refurbished, strategies are learned and tested, enemies are studied
and analysed, etc. Most of us don't do this in our spiritual life. We
tend to go on living just like every one else around us, and call on
God only when we face a calamity. Our spiritual muscles don't get
exercised, and our spiritual alertness cools down.
Let us make a distinction between severe calamities that force us to
go to God and the daily temptations that trouble us in daily life. In
our daily life we are tempted to tell lies, react in anger or
irritation, become anxious, jealous or bitter, entertain lustful looks
or thoughts, etc. Some of us may not even of think of such things as
temptations to sin! We aren't going to be able to overcome such
temptations if we aren't determined to. But if we are determined to
fight against temptations and overcome them, then we will also get
into the habit of watching and praying.
This is not just about praying. It is a whole attitude set against
sin. This will lead to preparations against temptation -- getting to
know God better, hearing His voice more clearly, understanding His
mind and His ways better, understanding more about our own weaknesses
and special tendencies towards sin, learning how others have managed
to cope with temptations, etc.
We can't hope to get much further on this way if we have no time to
'spare' for such things!
