Light is used to symbolise God, faith or holiness throughout scripture.
For thou wilt light my candle: the LORD my God will enlighten my darkness.
Psalm 18:28 (KJV)
A burning candle can light even the darkest of rooms. It can not just light a darkened room but can show those in the room what is around them, and can guide them to a place of safety and security.
God’s love is just like that – His love can brighten even the darkest of times. And if we trust him, he will guide us through those times to a place of safety in his loving arms.
