How do we know God's grace is sufficient for our needs?

The sufficiency of God's grace is vividly demonstrated in the account of the woman in Luke 8 who had suffered for many years without healing. Her faith, though simple, was met with God's grace manifested in healing. The scripture recounts how she pressed through a multitude to reach Jesus, signifying her desperate need for grace. God's merciful timing and response not only healed her bodily condition but also indicated the depth of His love and grace toward her spiritual state, fulfilling her true needs. As stated in Ephesians 3:20, God is able to do far more abundantly than we ask or think, highlighting His sovereign grace which meets our needs when we approach Him in faith.
