Our God is a personal God. And as a personal God, He will hear you when you call out to Him.
When you trust Jesus as your Lord and Master and Savior, He opens up the lines of communication between you and your creator. When you turn from your sins in repentance and turn to Jesus in faith—He becomes your high priest, your mediator, your intercessor. Because of what Jesus did for you on the cross, you can now talk to God like He’s your loving daddy—because He is.
God is the God of heaven and earth. He is great and awesome. He is supreme and majestic and glorious and wonderful. He is the only one who is to be hallowed because He is the only one who is worthy of our worship.
But despite that, we can talk to Him. He is our Daddy who loves us enough that He paid the ultimate price of sacrificing His only begotten Son that we might be adopted by Him as his children. And as His adopted children, He will never let us go.
Think about it—the all-powerful creator and sustainer of the universe delights in hearing us when we talk to Him!
