And there are seasons of life when you must fight for faith because all of these small things, usually money things, vie for faithlessness; push you and prod you toward faithlessness; become a reason to back down from what you know, and this season seems to be that for you now. BUT (and there is always a but) take heart, oh my soul, because the lord has been (so) good to you and you can fight this battle of faith and come out a victor; these hard places will be your cement, the sand that turns into rock; the testing of your faith makes perseverance and that's what you want to be at the end of your life...a persevere-er.
When the good news in all this new-tires-depleting-tiny-savings-just-in-time-for-Christmas gig is that in everyday, in every season, God is the faithful one and he has made this promise to you about his faithfulness not being dependent on your faithfulness. And you decided (while riding on brand new tires!) to trust God to provide in this month in ways that are new and creative and may not be full of what you're used to, but may be even better.
Because this is the advent, the wait...there is HOPE and it is COMING and you just have to have eyes to see it and a heart to say yes to it all.
Hold on, self. Your rescue is near!
