'Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin. Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.'
It’s not a sin to ask, “why?” God came to earth in the form of Christ and experienced the pain and darkness and difficulty that we experience. He understands.
Don’t blame God, trust Him.
