"it was by faith that noah built a large boat to save his family from the flood. He obeyed God, who warned him about things that had never happened before" (Hebrews 11:7)
In just the new testament alone there are 1050 commands, and they are all there for your benefit. God says things like, "love your enemies" and "forgive the people who hurt you" That's not easy!
There are lots of commands in the Bible that seem difficult, unreasonable, unrealistic, unachievable or even impossible. He says it because he knows best and knows what will make you happy more than you do.
The question is: do you trust God? If you do, learn to obey his words and you will not miss out of the blessings made available for you.
If you obey the commandments even when it seems absurd and the exact opposite of your natural tendency, then you're going to grow in faith and get blessed in all areas of your life.
