As you look back over this last year, there are probably things that happened during the year that you could have prevented. For example, you reacted instead of responding in love to words a person spoke to you.
There is no way you can undo the past, but you do need to come to the place where you can resolve to do better in the present. The major fruit of the Spirit that you and many others need the help of My Spirit is self-control.
Self-control includes being able to control your speech. No man can tame the tongue, but you and everyone can ask My Holy Spirit to be your tongue trainer in this next year. My Spirit can help you speak the truth in love and speak edifying words instead of destructive words. Submit your tongue to My Spirit's control daily in this next year and you will have a fruitful year.
