“Now the sons of Israel journeyed from Rameses to Succoth, about six hundred thousand men on foot, aside from children. A mixed multitude also went up with them, along with flocks and herds, a very large number of livestock.” Exodus 12:37-38 NASB2020 https://bible.com/bible/2692/exo.12.37-38.NASB2020
When the Israelite slaves of Egypt left Egypt, delivered from the power of the Egyptian rulers by the hand of God, they took with them other slaves, other outcasts, other peoples, including some Egyptians, who were likewise suffering in the land and who also were impressed by the power of the God of Israel. These non-Israelites were required by God to be circumcised like the Israelites in order to become one people with Israel. In this way the One True God would lead His people in His ways for His glory. Those who refused to conform to the laws of God were removed from the people of God for the Lord Who is God decides how His people are to live. This is true today. Heaven rejoices when one person, any person from any land and any social status, repents and calls Jesus Lord and Savior, following Him in obedience to all of His commands. God loves the world, made evident by coming to live among us as one of us and to sacrifice Himself for all of us in order that those who would repent of their disobedience and turn toward God to live in obedience to Him could live forever with Him and with all those people from all of time who made the same commitment. The love of God and the grace of God has always been for all nations, no one is excluded from God’s love for He has made all people from one man and one woman. The will of God is for all people everywhere in the world to know Him and to love Him and to live together before Him as brothers and sisters. The work of the Christian is to make this love of God, this will of God, known to all people and to invite all people to repent and live in right relationship with God through Jesus the Savior, Who is God.
