We must be careful to let the Holy Spirit do this searching. If we try to search our own hearts, we are apt to fall into one or both of two traps. The first is the trap of morbid introspection. Introspection can easily become the tool of Satan, who is called the "accuser" (Revelation 12:10). One of his chief weapons is discouragement. He knows that if he can make us discouraged and dispirited, we will not fight the battle for holiness. The second trap is that of missing the real issues in our lives.
