Separation Unto The Lord
We have been called to be priests unto God , a holy priesthood that is set apart from the world and it's interests, devoted to our High Priest, Yeshua the Messiah.
As Peter said, "But as He who called you is holy, you also be holy in all your conduct, because it is written, "Be holy, for I am holy''"" 1 Peter 1:15-16
"And you, who were once alienated and enemies in your mind by wicked works, yet now has He reconciled in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight - if indeed you continue in the faith grounded and steadfast, and be not moved away from the hope of the gospel which you heard .." Colossians 1:21-23a.
Having been saved reconciled to God through His life but there is a process of sanctification which we need to go through to redeem our souls from the corruption of this world. As Paul says,
"Therefore my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling, for it is God who works in you both to will and to do of His good pleasure''." Philippians 2:12-13
With this promise and prayer if we continue to walk with Him: "Now may the God of peace Himself, sanctify you completely, and may your whole spirit, soul and body be preserved blameless at the coming of our Lord, Yeshua the Messiah. He who calls you is faithful, who also will do it''" 1 Thessalonians 5:23-24
We need to give earnest heed to the things we are taught in the Word, taking hold of the precious promises which are given to us so that we might be partakers of the divine nature.
If we do that we will secure our election and our calling into the everlasting kingdom of our Lord and Saviour, Yeshua the Messiah. 2 Peter 1:2-11
