Why did apostle Paul connect Hagar with Sinai and Jerusalem in Galatians 4? Was it to free believers in Yeshua (Jesus) as God’s Messiah from obedience to God’s Law?

Abraham obeyed God and had himself and all the men in his household circumcised and they all agreed to do it, including Ishmael. In the flesh, there’s no reason for circumcision, but if you believe in God, there’s every reason for it. Actively trusting God’s words — called “faith” and “belief” — is what makes one righteous.
Prayer serves as a vital means of two-way communication with God, grounded in Scripture, and requires humility and persistence. Historical references indicate that early followers of Jesus frequently recited the Lord’s Prayer, demonstrating active faith rather than passive belief. Key biblical examples emphasize the importance of trust and reliability in earnest communion with God. As believers express their faith, they should acknowledge God’s unwavering trustworthiness. Ultimately, our response to God’s promises should be one of acceptance and action, demonstrating true faith.
Deep trust in the God of Israel by those new to that trust and separated from God by their former lives is the thread weaved through the accounts of the healing of the Capernaum centurion’s servant, the raising of the Nain widow’s only son, Yokhanan’s message of repentance and the woman who anointed Yeshua with her tears and expensive ointment.
In chapter 10, use of two silver trumpets is explained, such as calling together the people to celebrate the New Moon and other appointed times. In chapter 11, the people of Israel call out for more than meat and manna, and God curses the cravers with copious quail followed by a plague.
Moses takes the time to sing God’s praises after they all went through the Red Sea in safety. They also faced their first test at Marah: Would Israel trust God completely or be bitter toward Him?
Acts 15 recounts a “watershed” moment among believers in Messiah Yeshua (Jesus) — should believers among the nations be allowed into the assembly of Israel and how. These events didn’t happen in a vacuum. Events from Acts 1–14 — Peter’s encounter with Cornelius and Paul’s first tour of Asia Minor — led to this momentous ruling by the elders. The passage from Amos 9 of restoration of a tabernacle for all believers is important. The Yerushalayim council ruled that we mustn’t “trouble” new believers as they learn Torah.
