When God adopts us as His children, granting us the Holy Spirit, He grants us certainty. The trick is to walk in what we know to be true, rather than what we feel at the time.
Faith is the ability to look at any situation, face any kind of "feeling" about that situation, and still choose to believe the Truth that we know. Faith is the assurance of things hoped for and the evidence of what is not seen. So says Hebrews 11. But the ability to walk in certainty requires constantly reminding ourselves of that truth.
It is difficult to be in a crazy circumstance and hang on to that. But I think it is even harder to live this in the everyday. I mean, when a hurricane completely destroys your house, you don't have much but your faith to fall back on, so to speak. The thing in Proverbs 3:5-6 - Trust in the Lord with all of your heart, and lean not on your own understanding; In all of your ways submit to Him and He will make your paths straight - is eaiser to see when it is all you can see. But when you're in your everyday life, and just going through the normalcy of it, and everything around you is the familiar, normal stuff, and you have plenty of knowledge about what is going on and such, it is hard to remember that you're God's child. And when a question comes in the everyday, it is harder to pause and ask God. But we should, right? I mean, He is there all the time, and He always knows the answer.
Anyway, that's what I was thinking. Walking in the certainty of being God's child requires teaching ourselves to do that in all of the realms of life.
