If Mark 11:24 Doesn't Mean "Faith Only" Then Why Would John 3:16?

Jesus said in Mark 11:24 "What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them." Even though the only condition stated in the verse for receiving what you pray for is "believe" that your will receive them, nobody thinks that is the only condition for such.We all know other passages state other conditions for our prayers being answered, for example:· I Pet 3:12 "For the eyes of the Lord are over the righteous, and his ears are open unto their prayers: but the face of the Lord is against them that do evil."· James 4:3 "Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts."· I John 5:14 "And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:"So if everybody can see Mark 11:24 doesn't mean "believe only," then everybody ought to also be able to see that passages like John 3:16 don't mean "believe only." Both Mark 11:24 and John 3:16 state a required condition (believe) for the benefit under consideration, but do not state all the required conditions. They are exactly the same in the respect we are talking about. We must take all the Bible says on both prayer and salvation to get a complete picture.
