Read Isaiah 58-61
Behold, the LORD'S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear: But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear. Isaiah 59:1-2
The hand in Scripture is a picture of strength and authority. Salvation is of the Lord, and it is through His hand – His power – that we are saved. The problem, then, is with us and not with God.
It is our sin that makes us break relationship with the Lord. While He will never turn completely away from His children, He is disappointed when we choose sin over fellowship with Him. That's how we build walls between ourselves and our Creator.
But the beauty of God is that He is all-powerful and all-knowing, so He will always be there to save, hear and forgive. When we return to the Lord's presence in repentance, we can find mercy and grace beyond measure. Then we can have fellowship and communion with God as before.
Is there anything in your life that has caused God to turn His face from you? If there is, change your heart attitude today and rebuild that relationship with the Lord. Our sin is the only thing separating us from perfect peace in God's presence.
