Love is a powerful force, and when love reaches the end of its strength, sovereign grace takes over and grants love's petition. That's the reason we have a Savior, God so loved the world, and His love projected to the world produced a Savior. God wanted so much to see you well, His love went out and produced an atonement for your sickness as well as your sins. It was the love of God that constrained Him to do it. Nothing is greater than love - it brings trust, it brings faith, and it brings pardon.
Love has no fear.
Love casts out fear. There's a great deal of fear among Christians, and this should not be. Fear stems from a lack of confidence, and a lack of confidence stems from a lack of faith. God wants you to cast your cares upon Him, for He careth for you. Love and trust Him - this will cast out fear and enable you to overcome and serve Him with greater love.
