Isaiah 59:1 See, the Lord’s hand is not too short to save, nor his ear too dull to hear.
2 Rather, your iniquities have been barriers between you and your God,
and your sins have hidden his face from you so that he does not hear.
Some people I struggle to hear. Unless I can see their face, I cannot understand what they are saying. For many years I have augmented my hearing with speech reading, using clues about words and emotions people wear on their faces. Whenever practical, I prefer to talk face-to-face, rather than pick up the phone, because in addition to non-verbal clues, physical presence lowers barriers between people.
So also with God. But God is always present and ready to hear us, yet we put up barriers and hide our faces. But we fool only ourselves, for God still hears our voice and knows our heart. Thus we lose when our barriers hide God’s presence and muffle God’s voice.
How do you open yourself to God, when you have something to hide?
