Luke 4:13 When the devil had finished all this tempting, he left him until an opportune time.
When you show you are strong, others will see your strength. When you show you are weak, others may well take advantage of you!
God wants us to remain strong, not in our own strength, but in the strength He gives us through our faith in Him.
Jesus showed the devil He was fully relying on God and nothing the evil one could do would touch His human body.
