As a Believer, you are loved and favored by Jesus and He has looked, and is looking out for you. That alone is reason enough to give thanks. But, just incase you need more reasons, here’s more.
Concerning the Believer the Bible says, “And we know that all things work together for good to them that love God, to them who are called according to His purpose.” (Romans 8:28)
So, if you are unemployed today, even if it’s the result of an unwise decision on your part, no worries. Give thanks for the mercy of God, as He’s working things out for your good.
If you’re sick, no worries. Trust in the work of Jesus, because it is by his stripes that you are healed. (Isaiah 53:5). Give Him thanks for working the situation out for your good. Indeed Satan means it for bad, but God will use it for your good.
Remember the story of Joseph? His own brothers sold him into slavery. Yet in Genesis 50:20 Joseph’s testimony was ” …you meant evil against me, but God meant it for Good…”
No matter how life appears to you today, because you love God and he’s created you for his purpose, all that Satan intends as evil for you, God intends for your good. And everything you’re experiencing, have experienced, or will is working in your favor, because God loves You. And really, that’s all the reason you need to give thanks, though I’m sure you have many more.
