“We do speak a wisdom among the mature, but not a wisdom of this age, or of the rulers of this age, who are coming to nothing. On the contrary, we speak God’s hidden wisdom in a mystery, a wisdom God predestined before the ages for our glory. None of the rulers of this age knew this wisdom, for if they had known it, they would not have crucified the Lord of glory.” (1 Corinthians 2:6-8)
Paul continues by paraphrasing Isaiah, stating that no one has seen or heard or even imagined what “God prepared [in advance] for those who love Him.”
What did God prepare?
In his letter to the church at Ephesus, Paul writes: “For [God] chose us in Him, before the foundation of the world, to be holy and blameless in His sight. In love, He predestined us to be adopted through Jesus Christ for Himself.” (Ephesians 1:4-5)
God prepared for us adoption into His family. He prepared us “for Himself.” He anticipated our ultimate glory — and so continues to prepare us “to be holy and blameless in His sight.”
Paul writes, “We have redemption in Him through His blood, the forgiveness of our trespasses.” (Ephesians 1:7)
God prepared for us our “redemption.” He planned to save us in advance of our fall into damnation. He prepared us to be owned by Him as His “possession, to the praise of His glory.” (Ephesians 1:14)
“For this reason,” writes Paul, “I pray that [God] may grant you, according to the riches of His glory, to be strengthened with power in the inner man through His Spirit, and that the Messiah may dwell in your hearts through faith. I pray that you, being rooted and firmly established in love, may be able to comprehend with all the saints what is the length and width, height and depth of God’s love, and to know the Messiah’s love that surpasses knowledge, so you may be filled with all the fullness of God.” (Ephesians 3:14,16-19)
