God does test human beings, else we would never be tempted to sin

Though Satan is the source of temptations, God permits temptations to test our loyalty to Him and His word, and to aid us in our spiritual growth. Without temptations, we might never know our weaknesses and harbored inward sins that we must overcome..

Jas 1:13-15 KJV
13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
14 But every man is tempted, when he is drawn away of his own lust, and enticed.
15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
