Lifestyle Changes
To the world, God's people are peculiar to the rest of the world who do not walk in His ways. How so? We need to go back in time to Yahusha (Jesus) and His disciples, before "mainstream" religious organizations took over and integrated worldly practices into the Messianic community.
Some changes we can do now
Prayer Life
According to the Didache, the Apostle's guidance to the Messianic communities, especially Gentiles who are not familiar with God's culture, we are to pray the Lord's Prayer (Ref. Matthew 6:9-13) three times a day. Probably the practical way of remembering to do this is to place it at the beginning of our meal time. The Lord's prayer is much shorter than the Amidah and more comprehensive, in general.
Feasts and Worships
While the mainstream churches today make up their own holidays, thinking that they please God with their freedom to change God's laws and times, the Messianic communities have been keeping God's appointed times (Ref. Leviticus 23, 1 Corinthians 5:8). These practices were documented hundreds of years before the mainstream church institutions rose to power.
Dietary Choices
Believers in the Messiah were told not to touch any unclean things (Ref. 2 Corinthinas 6:17). This also applies to food, and as Peter learned, it does not go to the level of considering the Gentiles as unclean food (Ref. Acts 10:28-35). Following God's command on what to eat or not (Ref. Leviticus 7:22-27, Leviticus11, Acts 15:29) will definitely make a person peculiar.
Our Abiding in Yahusha (Jesus) is a continuing process
2 Peter 1:1-8 (KJV)
1 Simon Peter, a servant and an apostle of Jesus Christ, to them that have obtained like precious faith with us through the righteousness of God and our Saviour Jesus Christ:
2 Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord,
3 According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:
4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
5 And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;
6 And to knowledge temperance; and to temperance patience; and to patience godliness;
7 And to godliness brotherly kindness; and to brotherly kindness charity.
8 For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.
