Hebrews 4:12 "For the Word that God speaks is alive and active; it cuts more keenly than any two-edged sword: it strikes through to the place where soul and spirit meet, to the innermost intimacies of a man's being: it examines the very thoughts and motives of a man's heart.." (Phillips)
The Word that God speaks is Jesus Christ. All God wants to say, he said in Jesus. We are to listen. What does the word do or say? We are told here that the Word is both alive and active. Every time we read God's word in scripture or call on God's Word, Jesus, we find life and activity. Each reading can speak new thoughts and insights. Each contact can right something in our life through his life. Jesus is the way, truth, and life---we need all of those things through him.
God's Word also cuts and strikes. We are pruned and cleaned up by God's Word. We are rebuked and shown where change is needed. Because God's Word is Truth, we will not be allowed to hold on to lies and false teachings. We will be shown truth and expected to obey it.
God's Word examines our thoughts and motives. We will see ourselves as God sees us. It's not pretty. When we see ourselves naked and exposed before him, we will repent. Then we can see him welcoming us home as his children. God's Word is our salvation and our peace in Jesus Christ.
Thank you, LORD for your living and active Word that speaks life to us and into us through Jesus Christ.
