A Closer Walk

"Whatever you do, do your work heartily, as for the Lord rather than for men; knowing that from the Lord you will receive the reward of the inheritance. It is the Lord Christ whom you serve," Colossians 3:23-24 NASB. Whatever we do, do it heartily, as for the Lord. It is the Lord Christ whom we serve. Whatever we do, try hard. Give it our best shot.
What if we are retired? Well, retirement then is our work so, do it heartily. How do we do that? There is a high probability our Heavenly Father doesn't mean for us to sit around and feel sorry for ourselves. Within our capabilities, there likely is something we could do that we would be passionate about, or enjoy doing. Something that would serve our fellow man, or help out somehow. How about helping in the nursery at your church? Do you like holding and rocking babies, and playing with toddlers? How about helping in the kitchen when the church has the next potluck. Everyone enjoys a potluck. Or helping with the funeral dinners? This is a ministry to the grieving family members. There may be some who, due to afflictions or capabilities, may be limited in what they can do. For them, the Throne of Grace is open round-the-clock, 24 hours a day, seven days a week. When we can do nothing else, we can pray. But do it heartily, as to the Lord.
Maybe you could consider getting a retirement job. This job might be completely unrelated to your career. Try something new and different. A change of scenery can be refreshing. Helping others or working with others is uplifting to our spirits. It changes our attitude, and gives us a new or better outlook on life. Work is its own reward. Plus, you would get a paycheck to help out with the expenses, or to have a little spending money (those grandchildren will not spoil themselves!). I personally and heartily recommend and endorse this option. Again, work is its own reward. To quote Walt Disney's Seven Dwarfs, “Hi ho, hi ho, it's off to work we go!”.
How about trying something you have always wanted to do? Or going someplace you have always wanted to go? You might even want to try something you think would be fun or challenging. Whitewater rafting? Parasailing? Sorry to be the one to break this to you, but you are not getting any younger. And the years are getting shorter. Remember, Moses was commissioned by Almighty God to lead the nation of Israel out of Egypt at the tender young age of eighty. Staying within our capabilities there are many things we could do or try and still not be throwing caution to the wind; at least not completely.
So, whatever you do, do it heartily, as for the Lord. It is the Lord Christ whom you serve.
