In Joshua 11, an army is assembled against the Israelites, described as “a great horde, in number like the sand that is on the seashore, with very many horses and chariots.” Yet God tells Joshua “Do not be afraid of them, for tomorrow at this time I will give over all of them, slain, to Israel”. Joshua and Israel destroyed this army, “he left nothing undone of all that the Lord had commanded Moses”. Afterwards, Israel received their inheritance and then “the land had rest from war”.
Paul in 2 Timothy 1 also gives advice about fear, “God gave us a spirit not of fear but of power and love and self-control”. Like Joshua and Israel were encouraged not to be afraid because God was with them, so Paul encourages Timothy and us not to be afraid or “ashamed of the testimony about our Lord”. Paul could say “I am not ashamed, for I know whom I have believed… Follow the pattern of the sound words that you have heard in me, in the faith and love that are in Christ Jesus”.
