Your Heavenly Father would never call you to be or do something that was impossible. When He asks you to do something or become something, He gives you the means to do it.
"Be holy as I am holy"The Lord calls us to be holy as He is holy, to be holy in EVERY aspect of our life. God is holy and He wants His children to act like, and look like Him.
God chose you and made you to be holy as He is holy. You are God's holy priest, and He is building you into a living temple.
Hebrews 12:14 tells us to, "Make every effort to live in peace with all men and to be holy; without holiness no one will see the Lord."
May you know more of God's special favour and wonderful peace that passes understanding, as you grow in Him and become more of who you are in Him. Blessings to overcome, and become who you are in Him.
