God puts a desire in our hearts to know Him. When we respond to that desire and start looking for Him, He reveals Himself to us.
For I know the plans I have for you,” declares God, “plans to prosper you and not to harm you, plans to give you hope and a future. Then you will call on me and come and pray to me, and I will listen to you. You will seek me and find me when you seek me with all your heart. I will be found by you,” declares God. Jeremiah 29:11-14
Here is the story from the Bible about how God made Himself known to the world.
You can watch it in any language.
God first revealed Himself to me when I decided to accept a friends invitation to read the Bible with them. When I started to seek to know about God, God began to show me that He was real and that He loved me. I would encourage every person to take God up on His promise. If you seek to know Him with an open heart and mind, you will discover the God who loves you more than you could imagine, who has a plan for your good, and will help you with what you need when you pray to Him.
