“Have mercy on me, O God, according to your steadfast love; according to your abundant mercy
blot out my transgressions. Wash me thoroughly from my iniquity, and cleanse me from my sin!” Psalm 51:1-2
A Psalm of David, when Nathan the prophet challenged him about his sin with Bathsheba.
“Create in me a clean heart, O God, and renew a right spirit within me. Cast me not away from your presence, and take not your Holy Spirit from me. Restore to me the joy of your salvation, and uphold me with a willing spirit.” Psalm 51:10-12

NOTE: God had given David an understanding of the role of the Holy Spirit in living Christ-like and this is one thousand years before Jesus made it possible for our Heavenly Father to send the Holy Spirit to indwell believers as a result of His atoning sacrifice.
But also note what Paul says about living Christ-like, we are to forget those things that are behind us and focus on those things ahead.
“Not that I have already obtained this or am already perfect, but I press on to make it my own because Christ Jesus has made me his own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus. Let those of us who are mature think this way, and if in anything you think otherwise, God will reveal that also to you. Only let us hold true to what we have attained.” Philippians 3:12-16
John 10:10 says that Jesus came to give us life, freedom, and a relationship with Him. He is our only hope—the only source of true peace. Are you experiencing this peace? If not, that can change if you trust in Him as Lord and Savior, repent, and turn to Him (Romans 10:9).
Gordon Cove once challenged his audience: “You have not sought the Lord with ‘your whole heart’ until you have tried a protracted season of prayer and fasting.” Could a lack of prayer, fasting, and repentance be one of the hindrances to a spiritual awakening? Absolutely! Desperate times call for desperate measures.
Fasting doesn’t twist God’s arm, but it does bend our knee. There is simply too much on the line—a massive spiritual awakening is our only hope.
As G. Campbell Morgan said, “We cannot organize revival, but we can set our sails to catch the wind from Heaven when God chooses to blow upon His people once again.”
It’s time to break up our fallow ground and seek the Lord while He still may be found (Hosea 10:12).
“We prepare the sacrifice with a humble and contrite heart and God will bring the fire of revival.” shaneiIdelman.com
