Exodus 12:41 says, And it came to pass at the end of the four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the LORD went out from the land of Egypt.  The Israelites left Egypt after four hundred and thirty years.  That was a long time for people to be waiting for deliverance, but God did deliver them.  No matter how long it takes, Christ is returning again.  Verse forty-two states, It is a night to be much observed unto the LORD for bringing them out from the land of Egypt: this is that night of the LORD to be observed of all the children of Israel in their generations.  This was to be an important day for the Israelites to observe remembering God's deliverance.   As followers of Christ, we should always remember to honor God for His deliverance of us from the penalty of sin.  Verse forty-three adds, And the LORD said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof:  The Passover would be for the Israelites alone.  Salvation today is only available for those who accept Christ as Savior and Lord.  Verse forty-four continues, But every man’s servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.  Those who were servants bought for money who had been circumcised would be expected to observe the day.  As followers of Christ, we are not born into the nation of Israel, God's chosen people, but we are expected to live under God's law by our faith in Christ.  Verse forty-five continues, A foreigner and an hired servant shall not eat thereof.  Though those who were servants who had been bought were expected to observe the celebration, those who were just hired and foreigners were not.  Verse forty-six adds, In one house shall it be eaten; thou shalt not carry forth ought of the flesh abroad out of the house; neither shall ye break a bone thereof.  Nothing was to be taken away from the feast.  We today can take nothing physical away from our relationship with Christ, but we must simply live by our faith in Him.  Verse forty-seven says, All the congregation of Israel shall keep it.  No one in Israel was exempt from the feast, since it represented a time when they were all delivered from Egypt.  Likewise, no believer in Christ is exempt from celebrating his or her deliverance from sin by the death, burial and resurrection of Christ.  Verse forty-eight states,  And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.  Strangers had away to become the same as the Israelites before God.  They were to be circumcised and obey God's law.  There is a way for anyone to become part of the family of God, and that is by accepting Christ as Savior and Lord.  Verse forty-nine continues, One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.  All people were to be under the same law, and that was God's law, and the same is true today for those who follow Christ.  Verse fifty declares, Thus did all the children of Israel; as the LORD commanded Moses and Aaron, so did they. We are told that all the Israelites obeyed God's command.  Verse fifty-one concludes, And it came to pass the selfsame day, that the LORD did bring the children of Israel out of the land of Egypt by their armies.  That day, God delivered the people of Israel from Egypt.  The selfsame day we accept Christ, we are delivered from the power sin and the death penalty that it brings.
