why god always giving challenge in our life?

It is not God who gives us challenge. God never tempts. It is ourselves which create problems and challenges because of the lust of the flesh, lust of the eyes, and pride of life which are all of Satan. Any problem that we encounter boils down from any or all of these three. The most that is hard to overcome is pride of life. Try removing these three from your life, and see the result. But I bet only few can do away with all of these things. And so God provide us a way and what we should do are all in the New Testament.

God always gives us challenges in our life to make us strong. The more difficulties you face and resolve them by taking as a challenge, the more strong you become. Every little thing in this world has a purpose, my friend, and these challenges are one of them and the purpose-to make us strong. You dont provide all the money to a child, u educate him and give him some skills so that he earn money. Likewise when we pray to god to solve our problems, he gives us challenges so that we may become strong and solve our problems. Good luck.

It is only during our trials that we fully felt the presence of God in our lives. It's not that he leave us during our happy times. Most of the time it is us that forgets him when we are comfortable. Remember God is always good and if something goes wrong with our life it is because we fail to consult God or fail to hear God before doing something.

I believe God gives us challanges to make us better persons, also, it is his way of making us feel that no matter what happens, he'll make all things possible and we have to trust Him.
