I ask myself this question more times than I care to admit. This is a tough question because I feel myself being pulled in so many different directions, especially at this point in my life. I just graduated. Kayla was born. We are looking for God's direction in the midst of everything.
Recently, we just made the decision to leave the Mission Miami team. We were asking this question. Does God want us to continue with the team? Does God want to use us somewhere else? The crazy thing about this is that we thought we wrestled with this last summer when we made the decision to get on the Mission Miami team! So now what is the deal, God?
It basically came down to closed doors. Everywhere we turned, we found closed doors. The deciding factor was the door of funding for our work. We couldn't even make our monthly rent payment! This forced both of us to try and work full-time to cover our expenses, train full-time to prepare for Miami, fundraise full-time to actually get to Miami, as well as be full-time parents. We felt this was too much for us to handle at this time in our lives. It seems like God was speaking here. Is this what Luke was talking about when he says, " [Paul and his companions] tried to enter Bithynia, but the Spirit of Jesus would not allow them to." (Acts 16:7)?
Right now, we are asking this question again but in a different sense. Now that we are looking for ministry jobs, where do we go? Do we go to Vermont? California? Texas? Within Texas do we go to Grand Prairie? Huntsville? Wichita Falls? We are researching all these places to see how God can use our gifts most effectively. We will see how the hand of God works here, but probably only after the fact.
Conclusion: I believe the only way to be absolutely sure of the will of God is in the times that we are looking back at situations rather than in the situations themselves. In the meantime, we trust that He will guide our paths.
