I'm seeing this Psalm from a personal perspective. I've been praying for a renewal of my relationship with GOD and a problem area that i have is with my cussing, and negative thoughts. My daily meditation seems to center on "let the fruit of my mouth and the meditation of my heart be acceptable unto Thee oh LORD" (paraphrased?). My thoughts and negative verbalization (?) of them are the bitter herbs and poison asps of my Spirit. My background is real shady and i would be counted amongst evil-doers. That was over 10 years ago before The LORD gave me new life. Now, going thru turmoil of backsliding, i reach out to The LORD for help, for guidance, for strength, for conviction, for real love in my heart.....
