'Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
Why am I mentioning a secular artist's lyrics? The reason is because the chorus reminds me of how People change and they change their mind, but God doesn't change. God is unchanging. His grace is always sufficient. He will never leave us nor forsake us. He loves us unconditionally.
Katy Perry was singing about a relationship with a person. She was tired of this guy who was always changing his mind. We are human and therefore we are not perfect and we aren't always the same. Our relationship with God is much different though.
God's love is unconditional so it doesn't matter if we messed up again. He will still love us the same. He will never leave us either. He won't just one day decide to stop loving and caring for us.
It shouldn't be hard for us to trust someone who doesn't change, will always love us, and will always be there for us. Do we really let God have control of our life or do we still have one hand on our life because we are afraid to trust Him? We should realize that the truth that God is profoundly unchanging is a very important truth and it lets us know that we are in good hands.
