Nachum Ish Gam Zu. “Ish” is a Lashon of Chashivus. The person who is involved in Bitachon and Hashgacha Pratis is not Stam a nice Tamim; he is a special Chashuva person. Those who learn Shaar HaBitachon and are Osek in Inyanei Emuna and Bitachon should always build themselves up and be extra proud of themselves, for the simple reason that they are more involved directly with the Melech of the whole world.
Like the Rambam says that he’d rather teach Emuna than any other topic. He is also automatically strong and happy; he is close to Hashem, and it says: עֹזְו חֶ ד ו הְבִּׂ מ קֹמוְְֹדהי"אְטזְְכז there is strength and joy in His place. (Gemara). Also, he is extreme, that in the face of the worst situations he says Gam Zu L'tovah, and he expects Davka the best outcome. (Maharal).
And a Melech is known for extreme Bitachon, since the statement: אַפִׂ ילוְחֶ רֶ בְחַ ד הְמונַחַ תְעַלְצַו ארוְֹשֶׁ לְא ד ם,ְאַ לְיִׂת י א שְׁמִׂ ןְה רַ חֲמִׂ יםְְברכותְיְא “As impossible as your situation may seem, NEVER give up hope!” was said by Dovid and repeated by Chizkiyahu HaMelech. Being extreme in Bitachon is Malchus, and you’re a Chashuva “Ish”! Be proud! Rabeinu Yonah says that “standing” is the stance of a person who has Bitachon; we see that Bitachon is an Inyan of Chashivus in general.
Also, since his very name was Ish Gam Zu, we see that a person can have a constant involvement in these Sugyos (topics) and become a total “shtick” Baal Bitachon, who monitors every move in his life based on the principles of Bitachon.
