Is God perfect or can he change his mind?

What do people mean when they say that God is perfect (Matthew 5:48)? What does modern Christianity teach about its existence and its character that is not biblically accurate?
Perhaps the most common attributes of perfection that people have associated with God are his power, love and general character. The Bible confirms that he has perfect power, which means that he can do anything he wants (Luke 1:37). Furthermore, the existence of God is a living definition of selfless and impeccable love (1Jn 4: 8, 5:20).

The scriptures also support the belief that God incarnates perfect holiness that will never change (Malachi 3: 6, James 1:17). Consider, however, the following two definitions of divinity that many believe to be true.

AMG's Concise Biblical Dictionary states that "the immutability of God means that ... there is no way that none of his attributes can become greater or lesser. They cannot change ... (He) can neither increase nor decrease in knowledge, love, justice ... "The Tyndale Bible Dictionary declares that God is so perfect that" he does not undergo any change from within or from anything outside of himself " . This article will discuss two main examples that refute these claims.

One day the Lord, in human form, decided to make an unexpected visit to his friend Abraham (Genesis 18). As they spoke, the Lord revealed that he had heard about the sins of Sodom and Gomorrah (verse 20). Then he said: "Now I will go down and see if they have done entirely according to their cry ... And if not, I will know." (Genesis 18:21, HBFV). God undertook this journey to determine if what he was told was true or not ("And if not, I will know").

Abraham then quickly began to trade to save the righteous in the cities (Genesis 18:26 - 32). The Lord declared that if he found fifty, then forty, then up to ten, the righteous one would spare the cities. If he had perfect knowledge that cannot be increased, WHY did he have to go on a journey of research of personal facts? If he is constantly aware of every thought, in every human being, WHY did he say "if" he found a certain number of righteous people?

The book of Hebrews reveals fascinating details about the plan of salvation. We are told that it was God the Father who determined that Jesus was made "perfect through suffering" (Hebrews 2:10, 5: 9). It was mandatory (required) that the Savior of man become human (2:17) and be tempted like us (4:15). We are also told that although Jesus was God in the flesh, he learned obedience through his trials (5: 7 - 8).

The Lord God of the Old Testament had to become a human being so that he could learn to empathize with our struggles and to fulfill his role as a merciful intercessor flawlessly (2:17, 4:15 and 5: 9 - 10). His struggles and sufferings changed profoundly and improved his character for eternity. This change qualified him not only to judge all humans, but also to save them perfectly (Matthew 28:18, Acts 10:42, Romans 2:16).

God is powerful enough to increase his knowledge whenever he wishes and be indirectly updated on events if he so desires. While it is true that the fundamental nature of the justice of the Divinity will never change, important aspects of their character, as in the case of Jesus, can be profoundly expanded and enhanced by what they experience.

God is truly perfect, but not in the way most people think, including much of the Christian world
