Titus 2 instructs us, among other things, to be "pure."
I read in book once that CS Lewis once said, "The good man is sorry for the sins which have increased his need. He is not entirely sorry for the fresh need they have produced."
Today I will praise the Lord for His everlasting kindness and forgiveness. I need Him more today. Or at least, I am more aware of my need. While I'm not really sure about the truth of this quote, or even how Biblical it may be, I have to admit that true repentance and subsequent forgiveness are unmatched in their ability to keep me humbly seeking Him.
As Paul said, it's not like we're supposed to sin so that grace may abound (may it never be!). But instead of wallowing in the ways I frequently fail my God, I can look to Him and be awed by His glorious grace. The grace that washes away all sin- every unrighteousness- as He is making me more like Jesus. I can look to Him and trust that His forgiveness is complete and sufficient. I can cry out to Him, "change me!" and know that He is already in the process of doing just that.
That's why I worship Him today. He is worthy, beyond worthy, to be praised every moment of every day. That's just why I happen to be praising Him today.
Hallelujah to the God of abundant grace!
"He predestined us to adoption as sons through Jesus Christ to Himself, according to the kind intention of His will, to the praise of the glory of His grace, which He freely bestowed on us in the Beloved. In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace which He lavished on us." Ephesians 1: 4-8a
Why are you worshiping today?
