How can we handle our fears? By believing God's promise.
"Fear not, for I am with you. Do not be dismayed. I am your God. I will strengthen you; I will help you; I will uphold you with My victorious right hand." Isaiah 41:10, TLB
Yes, be bold and strong! Banish fear and doubt! for remember, the Lord your God is with you wherever you go." Joshua 1:9, TLB
"We need have no fear of someone who loves us perfectly; His perfect love for us eliminates all dread of what He might do to us. If we are afraid, it is for fear of what He might do to us, and shows that we are not fully convinced that He really loves us." I John 4:18, TLB
The LORD is my light and my salvation; whom shall I fear? the LORD is the strength of my life; of whom shall I be afraid? When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell. Though an host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident.
