In Nehemiah ch.9, the Israelites had finished building the temple and the walls. They the word of God to the whole congregation and found and ordnance to keep the feast of Tabernacles. The feast was to prepare their hearts to repent of their sins. And on the day of Atonement, Yom Kippur, the whole congregation was to approach God and repent. They gathered at the temple and the levites and priests led them in worship and praise to enter in the presence of God. They began to repent of their sins. The priests began to count their sins from Abraham until then. The Law is the knowledge of sin and repentance. And John the Baptist came preaching repentance for the remission of sin. Jesus came and died for us to recieve grace after we repented of our sins. So that we can enter into the kingdom of God. This is God’s plan for everyone. And all you have to do is turn to God and repent and believe Jesus.
