Glenda and Robert Lennon were four miles off the coast of Florida fishing alone from their yacht. Glenda decided to take a swim and soon found the current had carried her too far out from the boat. Her husband, hearing her cries, without thinking dove in and swam to her, but then realized they were both being carried out. He was a champion swimmer, but not she. They made a plan. He would swim against the tide to keep the boat in view until the tide ceased and he could reach the boat. She should save her strength and just float with the tide and he would come and get her. He fought the tide for six hours and just as the boat was about to disappear on the horizon the tide turned and his strokes carried him to the boat exhausted. The sun had set. His searching was futile—he could not find his wife. The next day on one last effort of search, the search party found his wife—twenty miles out and still alive. It was an incredible story.
What it illustrates is this: Christians who just float never stay in the same place. Christians who disobey verses 5 - and beyond - do not apply themselves with diligence to grow and bear the fruit of faith drift into great peril. We must strive even to stand still, the tide of temptation is so strong.
Robert Lennon survived this ordeal because he made every effort to swim against the tide and stay within range of his boat. And when he had spent all of his strength to make progress against the tide - the tide shifted and carried him to his rescue!
As a result of his persistent effort to swim against the tide, not only was he rescued BUT his wife also was rescued!
When Peter urges these believers to "make every effort" to add to their faith he is encouraging them to swim against the tide - the tide of temptation, the tide of apathy, the tide of discouragement, the tide of doubt - any of which will cause them to drift from the safety and security of a relationship with Christ.
Should they be lost or set adrift they would not be able to rescue others.
How about you? Are you swimming or are you drifting? Are you making progress against the tides of opposition or are you being pulled under by them?
"Make every effort to add to your faith....."
