Matthew 6:24 (KJV) No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
Have you ever made a decision based on bad information? We all have. It's disastrous when that happens; it cuts deep and makes us feel extremely foolish. We know that we didn't intend to do wrong; we did the best we could with what information we had. What we had just wasn't good enough.
Unfortunately, many people go about life with a costly false assumption. It's the assumption that, if you'll pardon the use of an old restaurant slogan, they can have it their way. They think that they can go to church and curry God's blessings while going out throughout the week and enjoying the sins and pleasures of the world.
The problem with this assumption is that it's less a question about whether it's God or the world and more a question whether we really believe what God says or not. God promises to meet and supply our needs and to provide us with joy and peace. When we try to hold onto the world or a few pet sins, what we're really saying is that we don't think that God can really provide the joy that we're looking for. We're saying that the world can supply what God cannot, and that's a dangerous position to take.
Who really has your best interests at heart: God or the world? Why are you trusting what the world says will bring you joy? Proverbs tells us that stolen waters are sweet and secret bread is pleasant, but that its end is death and destruction. The things of the world may seem like they'll bring joy, but that joy is fleeting and will leave you empty and unfulfilled. The things of God may seem counter-intuitive to what our culture tells us, but they provide a lasting joy that will have eternal rewards.
Are you trying to play the field? Are you trying to get God's blessings while chasing after the world? I can tell you now that it'll never work and that you'll only make yourself miserable. Take a few moments and examine your life. Are you trusting what God says? If not, then it's never to late to recenter your life and to make yourself right with Him.
