Sometimes life seems hard, unfair, and unrewarding. Our responsibility is not to complain, but to rise to the occasion and deal with whatever comes our way.
It is common today for adults in their twenties and thirties to shirk responsibility, to shirk maturity, and to generally fail to act their age. Here's a truth: anyone older than our world's children has a responsibility to be a role model for those children.
Now, a person doesn't have to be a Spirit filled Christian to fulfil this, do they? Maybe not, but to do it consistenly, with joy, with great depth of consideration, and to delight in serving others for the sake of God's great name, they do. We do. And it is arguably easier when you have the Spirit because you have power from above to accomplish all that is good.
It's a cliché but the acronym WWJD is useful here. Didn't Jesus always rise to the occasion? Aren't Christians supposed to follow his example? Then get off your X-box if you know you are on it too much and use your time responsibly to advance the kingdom. Do it!
