Holiness: exalted or worthy of complete devotion as one perfect in goodness and righteousness

1 Samuel 2:2 There is none holy as the LORD: for there is none beside thee: neither is there any rock like our God.

Only God is Holy in the sense of being absolutely perfect in holiness. Angels were made holy by God’s goodness. Saints in Old Testament became holy by the covenant relationship with the Lord. Saints are holy in the New Testament because God through his goodness in Jesus Christ forgives their sins and gives the Holy Ghost so that believers can partake of the divine nature. Angels who are holy and saints who are holy OT and NT are dependant on God’s goodness to be holy. However God is not dependant on any body for his holiness. God is an eternal Holy Being without beginning or end.

Saints can be tempted to do evil. Even Angels can choose to do evil. Satan chose to do evil. The Question is did satan  tempt Angels?. Before some of the Angels sinned in rebellion against God. Would not they have been been tempted?. Satan his the tempter. But God is absolute perfection. It is impossible for him to choose to do evil. God is without sin. In fact God cannot even be tempted with Evil (James 1:13). God came to exist as a man Jesus Christ to get the victory over temptation. Jesus was not tempted as God although to his deity he was God. He was tempted due to his human nature.

What does it mean for Christians to be holy?

Holiness: To be set apart from worldliness and sin. And to be dedicated to God.

1 Peter 1:16 Because it is written, Be ye holy; for I am holy

We as saints are to separate ourselves from sin and worldliness. And dedicate our life to God. We are to live by the Lord’s standards not the standards of the World. As saints we need to grow by going from glory to glory. By having a relationship with God. Feeding ourselves with the word of God

God has chosen us to be saved through santification. We are to live and be obediant to God by Faith that we can live holy lifes.

2 Thessalonians 2:13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:

We are to be holy to be different from the world, a holy nation, royal priesthood and a peculiar people.

1 Peter 2: 9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
