The purpose of arming ourselves with Christ’s mindset is to cease from sin. We know that the believer will cease from sin entirely at death when the body of this death which sins so constantly is taken away from him, but this is not the time that Peter is thinking of, because the reason he gives for taking this mindset is that it will aid us in fighting sin while we are still living in the flesh.
The words are redolent with warning. We wouldn’t like any Christian to draw near in the twilight of life thinking, ‘I could have done so much more; I could have been so much better; I could have been so much wiser with my children, so much more self-controlled, so much more thoughtful, and now the time is gone.’ Listen to the apostle Peter: ‘that he no longer should live the rest of his time.’ He is speaking as though there isn’t long.
Are we directing our lives, conducting our lives for the Lord, every day giving it some thought? What am I doing? Am I going to accept every invitation that comes along? Am I going to plan time for the family, time for the Lord, time the Christian service? Are my actions fair? Do I follow pursuits that mean I heap too much responsibility upon my wife, or my husband, for the difficult things and the boring things and the chores? Am I fair? Have I started to give time to the concerns of growing lives? What do I do at my place of business? What is my witness like and my behaviour? Am I directing my life? Don't leave it too late, so that you look back with vain regrets.
