Isaiah 59:1-2

Behold, the Lord’s hand is not so short that it cannot save, nor His ear so impaired that it cannot hear. But your wickedness has separated you from your God, and your sins have hidden His face from you so that He does not hear. 

When we allow ourselves to drift away from God, the distance makes it harder for Him to hear from us. The static of sin can interfere with our communication, and we may have just turned off the receiver. Our relationship with God depends on us doing our part and staying connected so He can do His part and keep us on the right path.
