I’m definitely not a Buddhist. But I do think they’ve got one thing right. Having too many expectations causes unhappiness. But it’s a fine line that we walk as Christians , praying, trusting, and believing that God hears our prayers and wants to give us the desires of our hearts, but also knowing that God is in control. The Bible teaches this truth but not all churches do. It’s called God’s Sovereignty. We pray for what we think is best, but then , if we’re smart, we pray for God’s WILL to be done. That means that we acknowledge that our prayer could vary from God’s will. It’s not easy accepting that truth. People like to believe in the human idea of “free will”, which exists somewhat, but only as far as God allows it.
All this to say, I had a plan for the weekend, but it isn’t going to happen. I’m sure God’s plans are better, and I look forward to seeing what those might be.

Expectations can be future resentments.
God’s sovereignty always has our best interest in mind. God knows what we need when we are thinking about what we would like to have. His ways are always the best ways. He works all things for good for those who love and obey him, who have been called according to HIS purpose. We who are in Christ are free, but we are free to make His choices, not ours.
