" Praying with an unrepentant heart. The psalmist realized, “If I had cherished sin in my heart, the LORD would not have listened; but God has surely listened and heard my voice in prayer” (Psalm 66:18–19 NIV). Clinging to sin and stiff-arming God makes God stiff-arm us. If you hold on to sin and refuse to confess it, you cannot take full hold on God. "
