The past will always come back to haunt us, and it is very powerful. That is why there are many evil people who, in the fading years of their lives, commit suicide. It is because they cannot bear to look back at the evil they did when they had the choice – and strength – to do good. When you have the strength to do good, do good, and do it now. That is the only true investment that you can put up, not just in God’s heavenly Kingdom, but for your twilight years here on earth. The good you do now will be the reward of beautiful memories that you will reap in your fading years. You cannot afford those bad memories: in your twilight years, they will kill you.
