Some professing Christians have only a passing acquaintance with the Gospel. They can hardly give an account of what they hope for, or whom they hope in. And if they have some principles they take kindly to, they are so unsettled that every wind blows them away, like loose tiles from a housetop.
When Satan buffets and temptation washes over you like a tidal wave, you must cling to God’s truths. They are your shelter in every raging storm. But you must have them on hand, ready to use. Do not wait until it is sinking to patch the boat.
