I could have easily talked about other issues. The writer of James says that the piece of our anatomy that is hardest to control is our tongue. He says that this is the organ that can do the most damage with and needs to be tamed or controlled and if someone can do that then they have reached maturity. Our communication with and about each other is also a matter of ascesis of self control.
in conclusion... take a few moments to be still and ask the Holy Spirit to show you areas of your life which you need the spirits help in growing that fruit of Self Control. are there things that are out of control or have control of you that are impeding your christian life from growing or you from having the abundant life Jesus came to give us. Offer them up to God, and ask for the Spirit to walk alongside you and lead you to develop the fruit of the spirit and gain control over that area.
Secondly ask God to fill you afresh with the Holy Spirit, that you may know the Spirit's presence and leading more and more in your life and develop and grow love, peace, joy, patience, kindness, goodness faithfulness and self control in your lives.
