So if someone asks you the question: Give me a sign O God and how can I find you? God has already given the sign. 

What is that sign?

(A Faithful Version) 

Ezekiel 20:19. I am the LORD your God. Walk-in My statutes, and keep My ordinances, and do them,

20. And keep My Sabbaths holy; and they shall be a sign between Me and you, that you may know that I am the LORD your God.’

(A Faithful Version)I John 1:1. Everyone who believes that Jesus is the Christ has been begotten by God; and everyone who loves Him Who begat also loves him who has been begotten by Him.

2. By this standard we know that we love the children of God: when we love God and keep His commandments.

3. For this is the love of God: that we keep His commandments; and His commandments are not burdensome.

4. Now then, everyone who is begotten by God overcomes the world; and this is the victory that overcomes the world—our faith.

5. Who is the one who overcomes the world? Even the one who believes that Jesus is the Son of God.
