It says in Gemara, (Kiddushin 40b) as well as the Rambam (Hilchos Teshuva 3:4) "One should always view himself, and the world as well, as if it were a perfectly balanced scale of good deeds and not good deeds, and the next action one does will determine which way the scale will tip; either good, or ch"v the opposite"

This means, that in any given situation in which one finds himself, he is essentially totally equal and has the ability to tip the scale for the good!!

Although one may think to himself: I know I am full of Aveiros, I am most definitely weighed down to the bad (and perhaps by a lot!) how can I possibly say that I am equal and can tip the scale for good in just one second!?

The answer is: since you can do teshuvah in just one moment and just one second (זח"א קכ"ט ע"א) this means that at any given moment, you have the power to become a complete Baal teshuvah!

this point is also brought out in Gemara Kiddushin (49b), which says, if a man is Mekadesh a woman on condition that he is a tzaddik, the Din is that she is Safek Mekudeshes. Rashi explians because maybe he had a Hirhur teshuvah in his heart, which would then render him a complete tzaddik! (it is only since we cannot see what was in his mind at the time, that makes it a Safek) we see from here that it is possible to do Teshuvah and become a complete Tzaddik in one second with one thought!

so this means to us, that every second in which we find ourselves in, our whole past is dependant on this second; we can do a complete teshuvah in this coming second and turn around all that we have done in the past for good!

So essentially our scale is perfectly balanced no matter where we may find ourselves. for in each and every second, it is in our power to determine which way it will be tipped!

which way will you tip YUOR scale?
