Chazal tell us that we must keep geulah close to tefillah, (גאולה סמוך לתפילה) meaning that we should be careful to start the amidah (the Shemonah Esrei) directly after saying the berachah גאל ישראל - HaShem redeemed Israel. (the last of birchot shemah in shacharit)
(shemot 14:13) וַיֹּאמֶר מֹשֶׁה אֶל-הָעָם, אַל-תִּירָאוּ--הִתְיַצְּבוּ וּרְאוּ אֶת-יְשׁוּעַת יְהוָה, אֲשֶׁר-יַעֲשֶׂה לָכֶם הַיּוֹם: כִּי, אֲשֶׁר רְאִיתֶם אֶת-מִצְרַיִם הַיּוֹם--לֹא תֹסִפוּ לִרְאֹתָם עוֹד, עַד-עוֹלָם.
(shemot 14:14) יְהוָה, יִלָּחֵם לָכֶם; וְאַתֶּם, תַּחֲרִשׁוּן.
We usually think that we are praying to HaShem that we should be redeemed. What I only noticed this morning is that we just said that HaShem already redeemed us before we started to pray, (the Amidah) what gives? Clearly, we aren't praying that HaShem should redeem us. As we mentioned in the past, we should take it on blind faith that HaShem has already taken the necesary steps to redeem us, and we should be thanking him profusely in our prayers, delighting in the closeness of HaShem's salvation.
The two passukim above should be at the forefront of your mind whenever you worry about any kind of trouble at all.
הִתְיַצְּבוּ וּרְאוּ אֶת-יְשׁוּעַת יְהוָה, אֲשֶׁר-יַעֲשֶׂה לָכֶם הַיּוֹם - bear witness to the salvation of HaShem, which he will perform for you today. יְהוָה, יִלָּחֵם לָכֶם; וְאַתֶּם, תַּחֲרִשׁוּן - HaShem will do battle on your behalf, and you will be silent.If we can pray to HaShem truly knowing that He's already saved us, how great is the chelek of Am Yisrael!
