When you have an assignment from God--and we all do (cp. Mt 28)--the necessary thing is to press through the difficulties and hardships and continue to walk with the Lord. Overtime as you do this you will find that the Lord Himself will straighten your path and strengthen and empower your leadership, ministry, and service. This is what we see in the life of Moses as he walks through an incredible time of rebellion in Israel's early history with the Lord (Ex. 32), on to a mountaintop experience where he sees God's glory, and--after sometime with Him upon the mountaintop--returns, unbeknownst to him, with his face shining. Moses trusts God through the rebellion and the Lord himself strengthens and validates Moses' ministry and leadership among the people with a shining face. Moses focus, however, through it all is precisely what ours should be: not so much on his own face and its shining but on God's face and His glory. For Moses, the most important thing is not his own glory but rather talking with God and communing with Him.
