In an article by John Piper he shared the story of Glenda and Robert Lennon. They anchored their boat four miles off the Florida coast to do some fishing. Glenda decided to go for a swim. When she jumped in, she realized there was a powerful current pulling her away from the boat. When her husband heard her cries, without hesitation he jumped into the water and both of them were being drawn away from their boat. Glenda didn’t have the strength to fight the current, so she would float. Meanwhile Robert would swim against the tide to keep the boat in view until the tide changed, and then he would swim to the boat and come and rescue her.

He fought against the current for hours and just as the boat was about to disappear on the horizon, the tide turned and he was able to swim toward it. He finally climbed back on the boat totally exhausted. But as the sun set, he searched in vain to find Glenda. After hours of unsuccessful searching, he headed for shore before he ran out of fuel.

The next day the Coast Guard organized a search party, and a search plane found Glenda floating fifteen miles from where their boat had been anchored. She was exhausted but alive and was reunited with Robert a few hours later.

The point is this: Robert swam against the tide, and eventually made it back to the boat. Glenda floated and drifted for miles. The same is true for Christians. You must diligently swim against the current of our godless culture or you will drift away from God’s truth.

“But also for this reason, giving all diligence, add to your faith virtue, to virtue knowledge, to knowledge self-control, self-control perseverance, to perseverance godliness, godliness brotherly kindness, and to brotherly kindness love.” 2 Peter 1:5-7
