Matthew 12:36-37 (NKJV) "But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned."
Christians have become so very good at justifying their bad behavior, even their sinful behavior. In reality, we can justify just about anything in our lives to help relieve the pressure of the Holy Spirit bringing things to light for us to deal with them before Him in humility and self-sacrifice. It's sad.
We're told to not 'grieve the Holy Spirit' but every time we justify our bad behaviors (mostly our thoughts and words), we grieve Him greatly!
I realize this isn't the most comfortable reading but friend, listen: you have a chance to deal a death blow to pride that's simply masquerading as a 'good reason' for the sinful tendencies that have become all too common in your life. Today is the best day to humble yourself in that area, coming clean before the Lord.
Yes, you can justify anything you desire, but the truth is God always deals with reality. Truly, what I think is justifiable isn't really the core issue. The core issue is this: What does Jesus think? What has He said on the issue?
We need to be seeking Him continually and constantly!
