1 Peter 1 v 15 says “but as He who called you is holy, you also be holy in all your conduct”
When a person swears or promises by a thing greater than himself, it lends weight to what he says. He means that his word is as certain as the existence and power of the one by whom he is swearing. When one takes an oath by God or on the Bible, such as in a court of law, men recognize that God Himself makes the oath binding. We might not be thinking like this but it is actually what we are doing.
God swore by His holiness. “As He who called you is holy, you also be holy in all your conduct.” We find here that we are to be holy because He is holy. Holiness, like righteousness, is both given by God and achieved by us. Just as the vessels of the Tabernacle and Temple were holy, so are we when we are set apart for God when we become a Christian (I Corinthians 3:16; Colossians 1:22). Holiness, however, is more than a given state of being. It is a process that we must pursue throughout our Christian lives (Hebrews 12:14). That is why God says that we should become holy, to be holy in our conduct, wherever we are, work , home or play.
Holiness is what makes God what He is. It is not an attribute of God like love, joy, or omnipotence. Holiness is the ground, basis, and foundation of God. It is His uniqueness and totality, His deity, and divinity itself. It is the perfect purity of God.
What is hard , particularly during the 50 or so hours at work each week, is for me as a Christian to follow this instruction. But being hard does not make a thing not worth the effort and with Christ with me all things are possible!
Have a good week
