I am challenged over and over by people who do not believe in God's commandments. They will twist the scriptures to mean that we do not have to keep God's commandments in the Old Testament portion. 2 Peter 3:15-16 NKJV says, "Our beloved brother Paul, according to the wisdom given to him, has written to you, as also in all his epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures." There was no New Testament at the time this was written, so the scriptures that are being talked about are the Old Testament portion scriptures. They were twisting the Old Testament scriptures to their own destruction.
I believe the destruction it is talking about is more than the consequences of sin but of eternity in the lake of fire (see Revelation 21:8). We need the whole message and not just a positive message. God in His wisdom warns us of impending doom so that we do not fail at life. He would not be a good God if He did not warn us. Consider these scriptures in the Old Testament portion about the goodness of God.
God’s word gives us understanding for life. Psalms 119:130 NKJV says, "Your words gives light; it gives understanding."
God’s words and His commandments will direct our life so that we do better in life. Psalms 119:105-106 NKJV says, "Your word is a lamp to my feet and a light to my path. I have sworn and confirmed that I will keep Your righteous judgments."
God does what is right and that will not change. Therefore, His laws give us truth for life. Psalms 119:142 NKJV says, "Your righteousness is an everlasting righteousness, and Your law is truth."
God did not leave us to our own devices but gave us His commandments, they are truth. They were good in ancient times, and they will always be true. Psalms 119:151-152 NKJV says, "You are near, O LORD, and all Your commandments are truth. Concerning Your testimonies, I have known of old that You have founded them forever."
All of God’s commandments are true, they are the right way to live, and they will always be right. Psalms 119:160 NKJV says, "The entirety of Your word is truth, and every one of Your righteous judgments endures forever."
Desire God’s commandments and learn to walk them out in life. Psalms 86:11 NKJV says, "Teach me Your way, O LORD; I will walk in Your truth."
Want how God wants you to live life. God’s truths will help you. God is a loving God who will forgive those who want to follow His commandments. Psalms 25:5-6 NKJV says, "Lead me in Your truth and teach me, for You are the God of my salvation; on You I wait all the day. Remember, O LORD, Your tender mercies and Your lovingkindnesses, for they are from of old." Also, Psalms 25:10 NKJV says, "All the paths of the LORD are mercy and truth, to such as keep His covenant and His testimonies."
God’s word was good, is good, and will always be good. Numbers 23:19 NKJV says, "God is not a man, that He should lie, nor a son of man, that He should repent. Has He said, and will He not do? Or has He spoken, and will He not make it good?"
