No one really enjoys a difficult situation, be it anything. Being hard up on cash, humiliation, pressure at work, not being understood, a fight with a loved one. The Israelites didn't enjoy their time in the wilderness either. But the Lord leads us through the wilderness and allows us to remain there for a while. Unfortunately, we end up focusing on the wilderness and not Him. But only by focusing on Him can we allow ourselves to be taught the lessons He wants us to learn through trials. 

Deuteronomy 8:2-5 says:

2 You shall remember all the way which the Lord your God has led you in the wilderness these forty years, that He might humble you, testing you, to know what was in your heart, whether you would keep His commandments or not. 3 He humbled you and let you be hungry, and fed you with manna which you did not know, nor did your fathers know, that He might make you understand that man does not live by bread alone, but man lives by everything that proceeds out of the mouth of the Lord.4 Your clothing did not wear out on you, nor did your foot swell these forty years. 5 Thus you are to know in your heart that the Lord your God was disciplining you just as a man disciplines his son. 

The Lord allows trials in our lives because:

*Trials are meant to humble us.

*Trials show us what we really have in our hearts: the kind of people we really are.

*They test whether we keep the Lord's commands.

*They teach us to depend on the Lord.

*They are meant to bring glory to God.

*They are what the Lord uses to discipline us.

Ernest Hemingway once said: "Courage is grace under pressure."

Well, the Lord allows the pressure so that He can teach us the courage, extend to us His grace and be the strength to pull us through. He disciplines and moulds us only because He loves us enough to do so.
