2Chr 20:20 …Jehoshaphat stood and said, “Hear me, O Judah and you inhabitants of Jerusalem: Believe in the Lord your God, and you shall be established; believe His prophets, and you shall prosper.
The next day king Jehoshaphat and the people rose and matched to the battle ground armed with nothing but faith/confidence in God’s spoken word by His prophet. Faith was their shield. A man terrified of his enemies stood to encourage himself and his people. Rather than bid them to fight or stand up to them, he bade them to believe in the Lord God and give credit to His word in the mouth of His prophets. On this ground he assured them that they should prosper and be established.
The true courage which faith inspires a man will establish his heart in shaking times due to a firm belief in the power, mercy, and the promises of God. The word of Gods informs the heart to believe, prayers cement the word in the heart. Rom 10:17 “So faith comes from hearing, and hearing through the word of Christ“. Isa 26:3 “You will keep him in perfect peace, Whose mind is stayed on You, Because he trusts in You”
