Christians,does God really exist....?

Yes, and you know He does.

Yes. If He didn't, then the entire concept of true Christianity, as well as any hope for a decent future, would be a waste. Even apostle Paul noted a similar point when some were saying that Christ wasn't resurrected. (1 Corinthians 15:12-19)

I'm 99 and 44/100% certain of it.

SOMEONE or something caused us to exist; we call it God.

Hi Night city light, 

This a good question that I feel that one could really only answer personally. So you can decide for yourself whether God exits, I'm sending you two brief articles to read. The first presents several points to consider and reason on based on bible scripture. The second describes what you can do in your own life to perceive God's existence. If you have your own copy of the bible, I encourage you to follow along with the cited scriptures. 

I really hope this helps. The best in your search.

"Has Anyone Ever Seen God?", Bible Teachings, Bible Questions Answered, God

Things don't happen uncaused, and this world exists. It seems reasonable to believe it has a creator, a Creator that would rightfully be called God.

Yes...................

No.                                       

Yes. Jesus Christ is the One true God and Savior.

The truth is that death leads to heaven or hell, and the only way to heaven is through faith in Jesus Christ.

The Bible is very clear that no one can earn their way to heaven since good works do not pay for sins. See Gal. 2:16, Rom. 3:23-28, 4:4-5, Eph. 2:8-9, Tit. 3:5. The only way to heaven is by believing in Jesus for His free gift of eternal life. Jesus shed His blood on the cross as the full payment for our sins. He did all the work; all He requires of us is that we believe in Him. Once you believe in Jesus Christ to save you, you are secure forever!

Because we have all sinned against a perfectly holy and righteous God, we all deserve eternal separation from God in hell (Rom. 6:23). However, God loves us so much that He sent His only Son Jesus to die on the cross as our Substitute so we don't have to go to hell. Christ died for our sins, was buried, and rose from the grave three days later (1 Cor. 15:3-4). He gives eternal life freely to anyone who simply believes in Him for it. No one can be saved by doing good works. Salvation is by grace alone through faith alone in Christ alone (Eph. 2:8-9).

"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).
