Luke 1:37 says "For with God,nothing shall be impossible".
Yes,the word is very true that God can do all things but do you know He will not do some? Let me explain to you.
In a situation whereby you are calling God to do something for you but you are not getting answer quickly from Him,and it is as if God don't have power to do it. Ofcourse He has all powers.
But God has seen the future that we(human beings)doesn't see. He knows if He do what you are asking Him to do,it will later hurt or harm you at that particular time then it is as if God never loved you. He do loves you but He just doesn't want you to get hurt.
God's thought for us are good and not evil,to give us an expected end. He really wants the best for His children and doesn't want His children to go astray.
So I will urge you that you should be patience that He is working out the best for His children.
