There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.1 Corinthians 10:13 (KJV)
At no point has the Bible ever said that life would be easy. Yeshua did say that His yoke was easy to bear, but to do this we must be willing to accept Him as our Lord and Savior and walk His path. Through this path, we will be confronted by temptations. Such is the way of the world. However, when we are equipped with the full Armor of God, there is no temptation that we are not capable of overcoming.
