Some people are multi-taskers and some can't walk and chew gum at the same time. God is the ultimate multi-million-tasker and needs no reminders. Our days can seem so similar to us that time goes by before we even know it. There's a song lyric that goes 'You're gona miss this, you're gona wish these days hadn't gone by so fast.' How true.
Our lives are both a journey and a process through which God is working on us. Whether we surrender or resist to His will is our choice. We see His faithfulness sometimes in our past, but most things we'll never know why they occurred. Trust reminds us 'that He works all things for good, for those who believe in Him.'
