Unfortunately it is easy for Christian men to believe they don't display those types of characteristics (it is hard for us to believe what we can not see).
Our W10C recommends that we ask ourselves questions like these:
#1, do our words or actions 'rub others the wrong way'? #2, do we recognize our sin nature, our pride and ego, our 'rational' tendencies ? #3, do we see problems that are developing in our kids – as to self-centeredness issues ?
It all boils down to being able to see this in ourselves or in others.
Once recognized, we need to take action. How ? First, develop a proper perspective on 'self-will'. Second, if you are struggling with it, work to isolate the cause. And third, take action – if you really want to deal with this, you will work at starting what you need to do, stopping what you should and you will find ways to validate your progress.
And remember Galatians 5:26 ... “Let us not become boastful, challenging one another, envying one another.”
