Psalm 18:30 As for God, his way is perfect: The Lord’s word is flawless; he shields all who take refuge in him.
One thing many people struggle with is the fact that God is perfect; we live in a broken world where ever the most pious of people make mistakes – but God does not.
He made sure we had the truth written down for us and backed up with witnesses – more so than our judicial systems around the world!
Everyone who does trust in Him will not be disappointed in what He does and can do; but we find it hard to trust in someone, especially if we cannot see them!
