As long as I am inside the gospel, I experience all the protection I need from the powers of evil that rage against me. If is for this reason that the Bible tells me to ‘take up’ and ‘put on’ the whole armor of God; and the pieces of armor it tells me to put on area all merely synonyms for the gospel. That God would tell me to ‘take up’ and put on’ this gospel armor alerts me to the fact that I do not automatically come into each day protected by the gospel. In fact, these commands imply that I am vulnerable to defeat and injury unless I seize upon the gospel and arm myself with it from head to toe. And what better way is there to do this than to preach the gospel to myself and to make it the obsession of my heart throughout each day.
