Isaiah 41:10 Do not fear, for I am with you; Do not be afraid, for I am your God. I will strengthen you, I will also help you, I will also uphold you with My righteous right hand.’
Do not worry! Because He is with you, God's words to us as spoken by Isaiah, one of the first things this verse speaks to us is about not fearing because his presence is with us.
Jehovah lets us know that he is with us that he is present in every situation, and that because we forget that he is observed and that he is present, we fear when we see our enemy, who we can see as big, imposing, with weapons of strange war that can cause terror, but then the beloved Jehovah of hosts appears, and tells us "Do not be afraid, for I am with you".
That he wants to tell us with this, that He is more imposing, bigger, and with the right hand of his justice as a weapon of war. Hallelujah!
So do not fear, because he is with you and it is your God who strengthens you.
