Belief and obedience
And anyone who believes in God’s Son has eternal life. Anyone who doesn’t obey the Son will never experience eternal life but remains under God’s angry judgment.”
John 3:36 NLT

Belief and obedience go hand in hand. True belief results in obedience. Faith results in our salvation because of God’s grace and mercy – that is available through belief and obedience.
Faith = Belief & Obedience
This is because God’s grace and mercy offers us forgiveness for our sins. Receiving this forgiveness of our sins with a heart of belief results in grattitude towards God for this free gift of grace that we do not deserve because our lives are not blameless. This spirit of grattitude opens our eyes to the truth about God’s loving and merciful nature – not as a prison warden holding a list of rules over our heads – but as a loving Father, teaching us through the law that we need Him, that we need to be like Him in order to grasp hold of the blessed life eternal that He has for us (a life of obedience).
