Those who are baptized in Jesus do not need to strive after a new life. They have already attained new life through dying with Christ. But they do need to nurture that new life so it can grow and mature. That's what church is for. That's what Bible study is for. That's what prayer is for. It is like the Parable of the Sower. Many of those seeds sprouted up, but only a few grew into maturity. The rest withered and died.
A wealthy businessman was horrified to see a fisherman sitting beside his boat, playing with a small child.
"Why aren't you out fishing?" asked the businessman.
"Because I caught enough fish for one day, "replied the fisherman.
"Why don't you catch some more?"
"What would I do with them?"
"You could earn more money," said the businessman. "Then with the extra money, you could buy a bigger boat, go into deeper waters, and catch more fish.Then you would make enough money to buy nylon nets. With the nets, you could catch even more fish and make more money. With that money you could own two boats, maybe three boats. Eventually you could have a whole fleet of boats and be rich like me."
"Then what would I do?" asked the fisherman.
"Then," said the businessman, "you could really enjoy life."
The fisherman looked at the businessman quizzically and asked, "What do you think I am doing now?"
Are you striving after new life or are you already there, enjoying it, finding rest in Christ. If not I invite you to be baptized and share in the peace and rest only God can give.
