How do we know God's strength is sufficient for us?

God's strength is consistently demonstrated throughout Scripture, confirming that He equips His people for the challenges they face. For example, David faced Goliath not in his own strength but based on past victories where the Lord delivered him from the lion and the bear. He said, 'The Lord who delivered me from the paw of the lion and the bear will deliver me from this Philistine' (1 Samuel 17:37). Furthermore, as Paul writes in Ephesians, the same power that raised Christ from the dead works within believers, confirming that we are never alone in our endeavors. God's provision often comes exactly when we need it, illustrating His perfect timing and ability to supply our every necessity.
