Can A Saint Falsely Accuse God?

From Oswald Chambers:
" All the promises of God in Him are Yes, and in Him Amen..."( 2 Corinthians 1:20)
A person who is lazy in the natural realm is always critical saying," I haven't had a decent chance," and someone who is lazy in the spiritual realm is critical of God. Lazy people always strike out at others in an independent way.
Never forger that our capacity and capability in spiritual mattes is measured by, and based on, the promises of God. Is God able to fulfill His promises? Our answer depends on whether or not we have received the Holy Spirit."
