When you and your team are in the middle of a difficult time, it is ok to admit to them that you cannot see into the future. You will not lose respect if you tell them that you do not know how to navigate the challenges that are facing you. But if they follow you through the crisis in a failing effort, you may lose them for all future efforts.
There will always be a book claiming to have the magic key for your team's success. There will always be another team somewhere in the world that seems to have the formula for what you want. However, it is better for you to direct your team to the Scriptures rather than the latest bestselling strategy. In the Scriptures, you and your team can together call out to God and be instructed by the Spirit. You will not get credit for success, but your team will not give up if success takes longer than expected.
If you choose to lead your team through the latest successful methodology, you run the risk of ostracizing any team member who may hear something different from the Lord. I will never forget my team leader passionately instructing us not to invite additional lost people to our evangelistic Bible Study. He confidently told us to mobilize the lost attenders of the evangelistic Bible Study to start new evangelistic Bible Studies. Through the Bible, the Lord led me to a completely different conclusion. I rejected my leader's methodology. I disagreed with the book to which he was trying to conform us. Simply stated, I did not follow that leader for one more step.
Get your team to follow Jesus through a crisis--not you. He is big enough, strong enough, capable enough to get them where they need to be. Moses simply told the people what God promised. This was enough!
