How do I stop the enemy from making me doubt the Word of God?
It sounds as if you are already aware that your doubts are unfounded and that they are the product of Satan. As such, then the scriptures teach what to do:
And the writer of Hebrews echoes this when he writes:
These writers are reminding us that we must learn to resist such things and that the Lord allows the enemy to tempt us in this way to strength us and mature us just as our earthly fathers disciplined us for our own good. Rather than wish your trials gone, we recommend you take the opportunity to strengthen your will and mind by focusing on Christ and His word. As you do this, you will be better prepared to serve others.
Since you have a large following, the Lord will be particularly interested in strengthening you spiritually. You cannot gain this strength without enduring trials. Christ endured much greater than you, so you cannot complain about such things (since a slave is not greater than his Master). Pride is an ever-present concern for those who serve Christ, and even Paul required a “thorn in his side” to contend with his pride. Therefore, accept these trials of doubt and work to overcome them through the application of spiritual disciplines.
With respect to the specific doubts, you feel to God’s word, you will find that as you study scripture more, you will doubt it less. For example, have you taken our Isaiah Bible study online? If you take the study, we are confident you will have plenty of reason to cease doubting, for the text itself testifies to its accuracy and trustworthiness.
