So I've been a "Christian" for quite a while actually baptized since birth but actively believing for at least a decade. So throughout this time I haven't been able to find anything to do, I don't experience I have a calling anywhere and I don't have a cool testimony to share or anything. So how does one go from here?
God's will for you involves exactly where you are right now, what you are doing, where you are living, what church you are attending, your group of friends, and any activities you are involved in at church. The evidence that your will is totally surrendered to God's will is that you are content with your present state and circumstances and are totally peaceful. If you are fretful and wishing you were somewhere else, or hungering for an improvement in your circumstances, then this shows that you are not content with God's will for you at this present time.
Paul said that no matter what circumstances he found himself in, whether prosperous or in poverty, in fruitfulness or tribulation, he has learned to be content. Whether a person is sick or well, has a productive job or on unemployment, whether on the leadership team at church or is being passed over, one has to be content with where one is at.
The bottom line is that if God wants you to have different circumstances, He will change them. Once, when I desired to be in the ministry, but had decided on secular employment instead and saying to my wife that maybe I decided on a wrong direction in life, she said, "If you were meant to be in the ministry, you would have been."
God is the potter and we are the clay, and the clay never tells the potter, "'Why have you formed me like this?" We need to trust God that our present circumstances is God's will for us, and contentment comes when we surrender to His will and live and work within our present circumstances.
Marriages, even Christian ones, fail and break up, because one of the partners cannot accept marital problems and tribulation that happens. Things don't turn out the way they hoped and one morning the spouse wakes up and thinks they have married the wrong person, and so he or she breaks their vows and goes off in search of a more suitable marriage partner. This is evidence of a person not surrendered to God's will.
Of course I am saying that a marriage partner should not tolerate a spouse who is violent, gambling away the money, alcoholic, or is cheating. That spouse has already broken the marriage vow and it may be vital for the innocent spouse's health to ditch the marriage. If the spouse finds him or herself single for a long period of time afterward, there must be contentment with that state. If God decides to bring along another marriage partner, that will be up to Him, and it will happen if He decides that is best for the person.
