How can everything be good?

Trusting in G-d is based on the concept that The Creator gives of his benificence even to those who are not necessarily worthy recipients. How can we explain this?

The Tzemach Tzedek, the third of the Lubavitcher Rebbes, answered a person who begged him to bless his son who was fatally ill, “Think good and it will be good.” This means that the very act of ‘thinking good’ indicates trust in G-d and therefore G-d responds by providing good.

Developing true trust in G-d’s ability and will to provide us with physical beneficence is a spiritual service in and of itself. It means that a person relies and depends on G-d, leaving his future in G-d’s hands, rather than relying on any earthly cause, like a person in bondage to a master and totally dependent on him. His level of trust is so high that he/she doesn’t take into account natural causes, so that even if his/her situation is so serious that according to the laws of nature there is no way out, he/she will trust that G-d will come through for him, because G-d is not limited by nature, being the Creator.

The more we make an effort to develop this type of trust, the more G-d will be likely to respond by ‘coming through’ for us. In summary, no one is perfect, but that doesn’t mean that G-d ‘has it in’ for us. By working on trust, we earn and deserve to receive good, because we are thereby fulfilling G-d’s will.
To achieve this, it is very helpful to study Chassidic thought on a regular basis, and have a respected spiritual mentor.
