A solemn declaration by God or man that something shall be done or given. In Scripture, God's promises are expressions of His character and will — rooted in His unchangeable nature, they carry the force of an oath. The entirety of redemptive history is the unfolding of God's promises: to Abraham, to David, and ultimately in Christ. Every promise of God is "Yes" and "Amen" in Jesus (2 Cor. 1:20). Man's promises are binding acts of integrity, requiring fulfillment lest one sin against God and neighbor.
PROM'ISE, n. 1. In a general sense, a declaration, written or verbal, made by one person to another, which binds the person who makes it, either in honor, conscience, or law, to do or forbear a certain act specified; a word given to another for some benefit to be conferred on him. 2. Ground or basis of expectation. 3. That which affords expectation of future excellence. v.t. To make a declaration to another, binding oneself to do, give, procure, or forbear something.
Modern culture treats promises as provisional — subject to changing feelings, convenience, or circumstances. "I promise" has become little more than rhetorical emphasis rather than a binding commitment. Marriage vows are broken at will; political pledges are forgotten immediately; even the promises one makes to God are treated as suggestions. The biblical seriousness of sworn promises — that breaking them is a form of bearing false witness — has been largely abandoned in a culture that prizes authenticity of feeling over faithfulness of word.
