God takes holiness and covenant much more seriously than we often do. When we undervalue the need for faithfully following God in His Word and living as a holy people before Him, disastrous consequences enter our lives. God's communication, fellowship and graces are impaired or cut off from us- like an iron wall between us. If we are to fellowship with God we must fellowship with Him His way- and His way is by faithfully following Him in His Word in righteousness and truth!
