Should we have to have proof of God’s existence?

‎”At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven? And Jesus called a little child unto him, and set him in the midst of them, And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. And whoso shall receive one such little child in my name receiveth me.” Matthew 18:1-5

We are called to have faith like a child. A child believes things without needing proof.
For example; children believe in Santa or the Tooth Fairy because their parents/society teaches them that, even though we (adults) all know they aren’t real. But the children believe because they trust that we are telling the truth. (even though they are big fat lies)

I admit, at first I wanted some hard and fast facts or evidence in my life that God was working, but over the last year or so, with lots of prayer and wanting to change, God has revealed Himself in my life more and more.
He has really helped me out by answering a few prayers, one of them quite major, and I’m so grateful.
I think also, that the more I see Him working in my life and the more I fellowship with other believers, the more I am learning to trust in Him.
“And Jesus answering saith unto them, Have faith in God. For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.” Mark 11:22,23

I am learning more and more not to trust myself and my actions, but to believe that God has a plan for me and my life, and if I try to get ahead of Him instead of it being in His perfect timing, it will be disastrous.

Do you need proof to believe, have you got a testimony, or do you (for whatever reason) just believe?

“But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.” Hebrews 11:6
