“Is not my word like fire,” declares the LORD, “and like a hammer that breaks a rock in pieces? Jeremiah 23:29 (NKJV)
God compares His word to a hammer, therefore, let us look on the uses of a hammer so we can get a clearer understanding.
A hammer is a tool meant to deliver an impact to an object. The most common uses are for driving nails, fitting parts, forging metal and breaking up things into pieces.
To be effective the hammer must be in a strong hand that knows how to drive home nails, to tighten and fasten them also and breaks things in pieces.
So the Word of God in the hand the Holy Spirit will drive home and fasten the nails of peace, joy, love, faith, and hope.It will also drive home and fasten the promises of God in our lives. The word of God, like a hammer can impact our lives and cause us to be transformed. The word breaks up the rocky mountain that seek to stand in our way. God is the great One who hold the hammer to our lives; will fit and mend the parts of our lives and makes us stable, secure, and unmovable in Him .
