Change how you think - Sacrifice
Sacrificing for others is part of life. It's usually the small daily sacrifices we make again and again over a lifetime that have the biggest impact. Often those are the ones we may resent from time to time.
There is no value in resentment except as a reminder that we need to change our thinking. I know it usually takes me a while to get back into a positive mindset. Don't focus your efforts on dealing with the resentment. Just focus on releasing the grip you have on it. If you are open and willing, the Holy Spirit will help you change those thoughts from resentment to gratitude. However long it takes you to make the change, it's worth the effort.
Sacrifice gives us the privilege of following the pattern Christ has set for us. It's not only the right way, it's the way that works!
