Promise

[2] In the law of contract, an exchange of promises is usually held to be legally enforceable, according to the Latin maxim pacta sunt servanda.

And lastly, there are election promises, commitments that most people realize will later be shaped by politics and compromise.

Once acceptance has taken place, a binding contract has come into existence and both parties are legally bound by its terms.

Therefore, if by the time of the breach the price of the car has increased by 10%, A would be liable to pay B $1,000, assuming that B has not paid anything yet.

But a contract may only give rise to an undertaking by one party, as where A agrees to pay B if B finds a particular car which A has been trying to acquire.

[6] Christian theology regards the gift of the Holy Spirit bestowed on believers as the fulfillment of a promise made by Jesus.

[8] In Christian ethics, a distinction is made between simple promises and oaths or vows.

[10] Some groups of Christians, for example the Religious Society of Friends and the Anabaptist Churches (such as the Mennonites), object to the taking of both oaths and affirmations, basing their objections upon a commandment given in the Sermon on the Mount, and regard all promises to be witnessed by God.

[citation needed] In Surah An-Nahl, God forbids Muslims to break their promises after they have confirmed them.

However, when someone does break an oath, they are required to ask for forgiveness and make up for the sin by feeding/clothing 10 poor people or freeing a slave (which is nearly impossible today), or, if unable to do these, to fast for three days.

One of the four types of promises that are punished quickly is when you want to harm a relationship when the other person wants to keep it.

[13] As opposed to Kant, some Rossian pluralists believe that morality with regards to right and wrong cannot be formalized in writing.

[17] However, promises are often made with an intent on the speaker's part to convince a hearer to do something by holding out the prospect of a reward; threats by contrasts are often made with an intent to influence a hearer's behavior by holding out the prospect of a punishment.

In addition, certain characteristics of promises and threats, such as "magnitude" and "credibility", affect the probability that the target will gain compliance or failure.
