Here are great promises to think on! 

I Jn 3:22 And whatever we ask we receive from Him, because we keep His commandments and do those things that are pleasing in His sight.
23 And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment.
24 Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us.

Mark 11:24 "Therefore I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them. 

John 14:21 "He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him."

Heb 11:6 But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him. (NKJ)
