1 Corinthians 10:1-4 (ESV)
For I want you to know, brothers, that our fathers were all under the cloud, and all passed through the sea, and all were baptized into Moses in the cloud and in the sea, and all ate the same spiritual food, and all drank the same spiritual drink. For they drank from the spiritual Rock that followed them, and the Rock was Christ.
Also, I wanted to share this powerful little video I found on Marko's blog yesterday. It's 40 illustrations that represent Jesus' 40 days of fasting in the wilderness. It reminded me a bit of what many of us are going through with our various Lenten exercises (too a lesser degree most likely). Just remember, if during this time of sacrifice and extra time spent with God, you feel moments of joy, clarity, and peace mixed with moments of exhaustion, weakness, and temptation -- you're in GOOD company!
