I’ve come to understand over the past few years that Christianity is just as much an understanding of God as it is a relationship with God. It’s an awareness you’ve got to have of God and His presence around you. It is a daily decision to devote yourself to Christ, and to live as though you are set apart. I think that this verse is speaking to that. It’s holding us accountable and it encourages us to choose to be honest in our interactions with each other, to be authentic with the people around us.
Countless times I've told friends that I would be praying for them, but then I walked away and promptly forgot to pray for them and their situation. I'm not diligent enough. If you're anything like me your brain is going in a million directions at once, and that’s okay; it’s just what you do with it that counts. Other times I've accidentally offended someone, or hurt him or her because I was not being careful in the way I talked. I wasn't being mindful of the way my words could be perceived. Words are powerful things; they can be a blessing or a curse.
During this continued season of Lent, be authentic in your interactions; be genuine. Don't hide behind a cloud of false promises or oaths. “Say just a simple ‘yes, I will’ or ‘No, I won’t.’ Your word is enough. To strengthen your promise with a vow shows that something is wrong.” (5:37—TLB) Don't use God’s name flippantly trying to make yourself sound bigger and better then you are. God knows when you aren't being genuine, even when the people around you can’t tell. Be aware of Christ and look at where He is at work in and around you.
