God is always right and His word is always honest. He never commits unrighteousness so we must never accuse Him of it when we are suffering.
We can never truly cover up our sins so we must confess them and deal with them before we face Judgment.
But God is more powerful than the devil and He will not allow us to be tempted above what we are able to overcome. He will enable us to remain faithful if we strive with our whole hearts to do so.
