That means to be in a thankful posture towards the Lord, as well as, being thankful for what we have, not only focusing on what we don't have. If you take a moment to look at your life and what's around you, it's a good chance that you have many more blessings than you think. There are many people who don't have it as good as yourself. And just in case you're saying, no Sharon you truly don't understand what's going on in my life. Well let me tell you, I may not know all the facts, but I know there are people who have it doubly worse than you and someone who has it doubly worse than them. It's just the way of the world. Why? I don't know all the answers to the reason why. Yet I do know that God allows certain hardships in our lives to get the glory from us coming out of our plights. He wants to showcase our lives for others to see His goodness. Let Him use your life as a model of His awesomeness. He wants to bless you.
Remember Esther? She was an orphan who was raised by her cousin Mordecai, because both of her parents died. Imagine that. But God was with Esther and He blessed her in spite of her setbacks. Or perhaps myself, my parents died on the same day during the same year. And I'm still standing. God is with me and I know that for sure.
Consider those things when you think nobody has it worse. And consider those things when you feel like giving up. Stay with it and be thankful for the things around you that are good even if it's one thing. God can work with that.
