Ps. 119:160 All your words are true; all your laws will stand forever.
ALL means all. There is not one word God has recorded in the Scriptures that is not true. Like it or not, God has declared what is truth. He who tries to water it down or adapt it to fit his own desires does so at the risk of his soul.
Not one of God's laws will falter. God's ways and thoughts are unchangeable. God's Word will outlast all of creation. God is absolute truth. He is eternal Truth. He is the same truth that He always has been and always will be.
It is imperative for us to strive to understand the words of God as written. It is not our opinions that matter, nor is it an option for us to try to make it say what we want it to say. Many things God has spoken are beyond our ability to understand, but that gives us no right to question its authenticity or authority over us. We must study it diligently under the Spirit's guidance to try and discern what is being said. And if we can't understand some things, we know they are true because God said it and we accept them by faith.
Wise is he who is humble enough to admit he doesn’t have perfect understanding of all things. Our understanding is limited by our feeble minds. We understand things based on our own experiences and teachings in life. Wise is he who lets the Word speak for itself and accepts it as truth simply because God inspired it to be written. The more time I spend in the Word, the more I discover how limited my understanding really is. Often, the Lord speaks to me in ways that are outside of my comfort zone of understanding. It is by faith and not our sight that we are able to gain an understanding of God’s Word.
God gives us opportunity and all the resources we need to learn truth and he will hold us accountable for what we do with our opportunities. Ignorance is not an excuse for those who have been given opportunity and squander it away. All of God’s words are eternally true and will outlast all or our understandings of it.
