Small ministries often make the greatest difference. The most important light in my home is not the large chandelier in our dining room, but the little nightlight that keeps me from stubbing my toe when I get up at night. It's small, but it's more useful to me than the show-off light (My wife says that my favorite light is the one that comes on when I open the refrigerator!).
Because God is love, the most important lesson He wants you to learn on earth is how to love.
What gives me the most hope every day is God's grace; knowing that his grace is going to give me the strength for whatever I face, knowing that nothing is a surprise to God.
