30 “I can do nothing on my own. As I hear, I judge, and my judgment is just, because I seek not my own will but the will of him who sent me. 31 If I alone bear witness about myself, my testimony is not true. 32 There is another who bears witness about me, and I know that the testimony that he bears about me is true. 33 You sent to John, and he has borne witness to the truth. 34 Not that the testimony that I receive is from man, but I say these things so that you may be saved. 35 He was a burning and shining lamp, and you were willing to rejoice for a while in his light. 36 But the testimony that I have is greater than that of John. For the works that the Father has given me to accomplish, the very works that I am doing, bear witness about me that the Father has sent me. 37 And the Father who sent me has himself borne witness about me. His voice you have never heard, his form you have never seen, 38 and you do not have his word abiding in you, for you do not believe the one whom he has sent. 39 You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me, 40 yet you refuse to come to me that you may have life. 41 I do not receive glory from people. 42 But I know that you do not have the love of God within you. 43 I have come in my Father’s name, and you do not receive me. If another comes in his own name, you will receive him. 44 How can you believe, when you receive glory from one another and do not seek the glory that comes from the only God? 45 Do not think that I will accuse you to the Father. There is one who accuses you: Moses, on whom you have set your hope. 46 For if you believed Moses, you would believe me; for he wrote of me. 47 But if you do not believe his writings, how will you believe my words?” (John 5:30-47 – English Standard Version)

 
John the Baptist, the Father and the Scripture all testify about Jesus Christ. These are many testimonies given by God. Regardless of the realness of the testimonies, there are always people who do not believe in Jesus Christ. Sometimes, we have doubts and we disbelieve Jesus too. Regardless of how much evidence God has shown us, how strong the evidence are, we may still have a difficult time in believing and trusting God. The problem is not driven from external circumstances, it is from within. We are the obstacle to believe. Our mind fails to set on God. We do not have the will to seek and trust God, we rather trust people and ourselves. We do not have a heart to love God. We love many things else, but God. Our mind, will, and heart set us apart from God. They cause us to doubt and disbelieve the faithfulness and truthfulness of God. First step to believing Jesus starts with internal transformation.
