Dealing With Anger: Letting the Holy Spirit Teach Us Self-Control
Anger is something every believer has to face. It can rise up in our thoughts, come out through our words, and show itself in our actions before we even realize how much control it has taken.
The Bible reminds us that our flesh does not produce what is pleasing to God.
Romans 7:18 says:
For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
That is why dealing with anger is not just about trying harder. It is a spiritual matter. The flesh has to be brought under subjection, and that does not happen in one moment. It is a daily walk with God.
