“All that is good, all that is perfect, is given us from above; it comes down from the Father of all light; with Him there is no such thing as alteration, no shadow caused by change. ” James 1:17
St. James makes very clear distinction in his letter on the gifts that come from God and those that do not. Temptation and sin do not come from God, they come from the evil desires which wage war within us; whereas the gifts that come from God are pure, full of goodness and perfect. There can never be any change in God’s nature - He always remains the Father of all light, meaning that, till the end of time, all that is Light has it’s origin and source in Him.
