Does God give you an opportunity to serve only to add resistance later? Why? Nehemaih 1-4

Nehemiah 2:8b-10
"... And the king granted them to me because the good hand of my God was on me. Then I came to the governors of the provinces beyond the River and gave them the king’s letters. Now the king had sent with me officers of the army and horsemen. When Sanballat the Horonite and Tobiah the Ammonite official heard about it, it was very displeasing to them that someone had come to seek the welfare of the sons of Israel."

Nehemiah was given a burden by God (see 2:13) to rebuild the walls of Jerusalem.   He was in captivity and was the cupbearer for the king.  We have no information about how he was selected to be the cupbearer, however.  The cupbearer was to always be ready to supply the king with wine to drink.  He was to taste the wine prior to serving the king.  If one of the king's enemies had poisoned the wine, the cupbearer would die first.    When Nehemiah had requested that he be allowed to return to Jerusalem for a short trip, he was taking his own life in his hand.   The king, on the occasion, however, allowed it and even supplied him with letters he could take to those officials in the land to let them know that the king was in favor of this return to build the walls.  Even though God had put Nehemiah in the correct place to get the king's permission, letters and a  military escort, there were still those in the land who would want to oppose Nehemiah.   In one land, Nehemiah was honored and given great privilege for a captive in the land.   However, in another land, his home land, he is not treated with contempt, even though he had letters from the king giving him permission to rebuild the city walls.   Where we have God's grace on the one hand, we have Satan's work on the other.    God had turned the ungodly man's heart (the king) to allow the work, but God had permitted resistance in the land (Sanballat) to keep Nehemiah faithful in prayer and to test the will of the people.   We all want things to go smoothly in life, but that is not how life goes.   Smooth is for heaven.    We will have smooth some day.    Right now God is using us and moving us into situations of great favor, only to give us just enough resistance to keep us armed for battle.   Peter and Paul were given great doors of opportunity for the gospel and saw thousands, in single days, come to Christ, only to be beaten and imprisoned and flogged at the end of the day.  God is not here to make our lives smooth, but He is here to make our lives look like Christ.   Christ went through daily suffering just living among sin.   His finally suffering on the cross was for us.    God's pattern is to put us in places of great opportunity (maybe the cupbearer to the king) and to use that opportunity to work on His mission.    That work WILL BE  opposed by the enemy.   That is both a sign you are doing God's work and the grace of God to keep you humble, relying on Him and conforming you to the image of His Son.
