For every warning of judgement there is a message of hope and repentance. God wants us to turn from our sins and return to Him; He wants us to come before Him and say:
Have mercy upon me, O God, according to Your Lovingkindness; according to the multitude of Your tender mercies, blot out my transgressions. Wash me thoroughly from my iniquity and cleanse me from my sin. For I acknowledge my transgressions and my sin is always before me. Against You, You only, have I sinned and done this evil in Your sight – that you may be found just when You speak and blameless when You judge.
Behold, I was brought forth in iniquity and in my sin my mother conceived me. Behold, You desire truth in the inward parts and in the hidden part You will make me to know wisdom. Purge me with hyssop and I shall be clean; wash me, and I shall be whiter than snow. Make me hear joy and gladness, that the bones You have broken may rejoice. Hide Your face from my sins and blot out all my iniquities.
Create in me a clean heart, O God, and renew a steadfast spirit within me. Do not cast me away from Your presence and do not take Your Holy Spirit from me. Restore to me the joy of your presence and uphold me by Your generous Spirit. Then I will teach transgressors your ways and sinners shall be converted to You.
Open my lips, and my mouth shall show forth Your praise for you do not desire sacrifices, or I would give it; You do not delight in burnt offering. The sacrifices of God are a broken spirit, a broken and contrite heart – These, O God, You will not despise.
Taken from Psalm 51 (NKJV)
To an apostate, Godless, pridefull, self-righteous, self-reliant, and deceived people!
The Mighty One, God the Lord, has spoken and called the earth from the rising of the sun to its going down. Out of Zion, the perfection of beauty, God will shine forth. Our God shall come, and shall not keep silent; A fire shall devour before Him and it shall be very tempestuous all around Him. He shall call to the heavens from above and to the earth, that He may judge His people; “Gather My saints together to Me, those who have made a covenant with Me by sacrifice”. Let the heavens declare His righteousness for God Himself is Judge.
“Hear, O My people, and I will speak. O Israel, and I will testify against you; I am God, your God! I will not rebuke you for your sacrifices or your burnt offerings, which are continually before me. I will not take a bull from your house, nor a goat out of your folds. For every beast of the forest is Mine and the cattle on a thousand hills. I know all the birds of the mountains, and the wild beasts of the field are Mine. If I were hungry, I would not tell you; for the world is mine, and all its fullness.
Offer to God thanksgiving and pay your vows to the Most High. Call upon Me in the day of trouble; I will deliver you, and you shall glorify Me”.
But to the wicked God says: “What right have you to declare My statutes, or take My covenant in your mouth. seeing you hate instruction and cast My words behind you? When you saw a thief, you consented with him, and have been a partaker with adulterers. You give your mouth to evil, and your tongue frames deceit. You sit and speak against your brothers, you slander your own mother’s son. These things you have done, and I kept silent; You thought that I was altogether like you; But I will rebuke you and set them in order before your eyes.
Now consider this, you who forget God, lest I tear you in pieces and there be none to deliver; Whoever offers praise glorifies Me; and to him who orders his conduct aright I will show the salvation of God”.
