“Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ” (Romans 5:1) Dictionary will define peace as freedom from war, harmony, concord, agreement, calm, tranquility, serenity, quiet, undisturbed state of mind, absence of mental conflict, contentment, acceptance of one's state, and the absence of anxiety. Bible (Greek) word “peace" is eirene. It has the sense of "joining what had previously been separated or disturbed." Thus, it frequently is used to signify "setting at one; quietness & rest." so "peace not just freedom from trouble but everything that makes for a man's highest good." or inner satisfaction, the contentment & serenity that derive from living a full life. Hebrew primarily uses the very familiar greeting, “shalom”. Though it is also generally translated as a single word like peace, rest, favor, safe, health, welfare and prosperity, it has, "a basic meaning of totality or completeness including fulfillment, maturity, soundness, and wholeness." It suggests that the person is being blessed with fullness or that his character is maturing into the Image of God, who is perfect. Jesus said "Blessed are the peacemakers." The peace of Christ is born of truth. It is harmony with God. The world is at enmity with the law of God; sinners are at enmity with their Maker; and as a result they are at enmity with one another. But the psalmist declares, "Great peaces have they which love Thy law: and nothing shall offend them." Ps. 119:165. Men cannot manufacture peace. Human plans for the purification and uplifting of individuals or of society will fail of producing peace, because they do not reach the heart. The only power that can create or perpetuate true peace is the grace of Christ. When this is implanted in the heart, it will cast out the evil passions that cause strife and dissension. "Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree;" and life's desert "shall rejoice, and blossom as the rose." Isa. 55:13; 35:1. “To be at peace with God or being reconciled to God is to make certain heaven will be our home for eternity; to make certain that we are in right-standing with God. What we do about being reconciled to God will determine where we will spend eternity. Our decision to be reconciled to God is the most important decision we'll ever make in this life.
