One question that almost if not every believer has or will ask in their life is: "What is God's will for my life". Even those who do not know Christ have asked themselves this question. "What on earth am I here for?" It is clear that people want to have a sense of purpose for their life and even success and there is nothing wrong with that. My brother and sisters, let me share with you that your identity is in Christ. He is the one that created you and formed you, knit you together in your mothers womb.
Think of it like this: If you by a brand new t.v., how can you really know how it works? You may know the basics like how to plug it up and connect it to the dvd and remote, etc. However, I guarantee you that there are some special features that you will not know about unless you read the owners manual. Although you think you know all about that t.v. you do not, because you did not create it. Although it's your t.v., you still need that manual to tell you all about it. That's how it is with God, if we don't know Him (the creator) and seek Him (through prayer and His word) about the purpose of our lives, we will never know.
I encourage you to seek the Father and instead of asking what is His will for your life, ask Him what is His will period. The focus needs to be on God, not our life. Henry Blackaby, the author of experiencing God says: "Once you know God's will, then you can adjust your life to Him", not vice versa. " Once we know what God is doing, then we will know what we need to do!
