Deuteronomy 8:2-3 Remember how the LORD your God led you through the wilderness for these forty years, humbling you and testing you to prove your character, and to find out whether or not you would obey his commands. Yes, he humbled you by letting you go hungry and then feeding you with manna, a food previously unknown to you and your ancestors. He did it to teach you that people do not live by bread alone; rather, we live by every word that comes from the mouth of the LORD. 

Exodus 28:47 For the abundant blessings you have received from the Lord and serve Him with joy and enthusiasm. 

The tendency is to remember and dwell on the things which the Lord has not brought to pass rather than to dwell on the areas where God has given a breakthrough. Even though God may seem to be slow in coming or the breakthrough seems to be delayed but He is the the Lord who bursts through. He will bursts through the garrison / the walls of opposition. 

2 Samuel 5:20 So David went to Baal-perazim and defeated the Philistines there. "The LORD did it!" David exclaimed. " He burst through my enemies like a raging flood!" So he named that place Baal-perazim (which means "the Lord who bursts through")
