Hebrews 13:5-6 - "…for he hath said, I will never leave thee, nor forsake thee. So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me."
In the popular children's story Peter Pan, there is an imaginary place that is so ideal and perfect called Neverland. As believers, we too have an ideal "Never" land of our own. In fact, it's a "Never, Never" land. The only difference, it's not imaginary, it's real.
As described in Hebrews 3:5, it's a place in Christ that God promises to never leave us. Never. When things are going great, He's with us. When things are falling apart, He's with us. When we are doing everything "right", He's with us. When we're doing everything "wrong", He's with us.
He said it twice, "I will never leave you, nor forsake you", meaning never, never. God is saying to us in the strongest possible way, that He will never ever leave us or forsake us.
Still not convinced, look at this verse in the Amplified Bible: "…for He [God] Himself has said, I will not in any way fail you nor give you up nor leave you without support. [I will] not, [I will] not, [I will] not in any degree leave you helpless nor forsake nor let [you] down (relax My hold on you)! [Assuredly not!]"
No matter what is happening in your life today, God is with you. Living and abiding in you. Even if you have turned your back on Him, He will never, never leave you. He doesn't come and go based on your performance or behavior. He is committed to you. He loves you.
