Say hi to it. And remember that it will leave in a few days, as it always does. Analyze the last few days and the other, outlying, unrelated occurrences that have also made me feel off kilter...a fight with Joseph? Confusion or embarrassment socially or at school? An uncomfortable conversation with family? Etc. It seems when something is off there, it's easier for me to get down about my spirituality.
Think of the last time I was touched by something. The most recent time. What was it? (Today, my answer to this is the talk I listened to yesterday by Christofferson where he said if all we are doing is helping people who struggle, without sharing Christ, it's a good social justice goal, but that's all it is; it doesn't make a lasting, eternal effect. That touched me because I care so much about social justice, about doing good and helping others. And that's good. But the real justice, and I believe this I think, I can give to people, the real help and redemption, is giving them Christ. This thought will change nothing in the way I talk to or treat people. I'm not going to start praying about who I can invite to church. That doesn't work and doesn't work for me anymore. But I am going to have the personal faith and witness in my heart, and maybe someone will wonder or ask about it someday, and then I can share it.
Remember that I don't have to worship the way someone else does (or the way I think they do--although it may be very different from what it seems anyway!). Remember that I don't have to talk like other people. Remember that I don't have to worship the way I always have. Remember the unique, personal things that have been beautiful to me spiritually. Why are they beautiful? What are they. (For me, thinking about Jesus and the lent scriptures I've been reading to Eloise; thinking about how He loves me; thinking about how I feel when I pray. Thinking about the simplicity of the gospel in the NT. Thinking about Jesus being the one, main, only thing that matters.)
