John 19, among others throughout the Bible, proves the bible is true. There are too many truths throughout the bible for a man to know them all, but God shows us all a little.One that stands out to me in particular and has brought me to trust in Jesus with my body is Revelations 18:23. Sorceries translated means drugs, medication, pharmacists... and it is obvious to the casual observer that the whole world has given themselves over to drugs and medication.
Because they have no changes, therefore they fear not God. Psalm 55:19 As for me, I will call upon God and the Lord shall save me.
Jesus said the truth and his disciples responded, this is an hard saying who can hear it. John 6:60. Thank God for the King James Holy Bible. For it is not altered by man. You can study and translate back to the original Hebrew and Greek.
