Proverbs 19:20-21(New Century Version)
20 Listen to advice and accept correction,
and in the end you will be wise.
21 People can make all kinds of plans,
but only the Lord's plan will happen.
If for a moment you think that you are in control of your life, you are wrong. Yes, you do have a choice and a will to decide what you will do, but ultimately God has a plan and He will make sure that it happens as it should.
Sometimes this is hard to understand, especially when we face hardship or the death of someone we love, but often in His word God tells us that He will make things happen. We might as well focus on trying to do as we should, because the God will make sure we return to the plan He has for us. That is why many of us sometimes experience difficulty; if we are out of His will, He creates the way back into it.
Bottom line is this: listen to those God places in your life, and then commit your own plans to Him. Make sure that you seek Him and pray that what you plan to do is whay He desires. You will be better off for doing it His way.
