Romans 12:1

I BESEECH YOU THEREFORE, BRETHREN, BY THE MERCIES OF GOD, THAT YE PRESENT YOUR BODIES A LIVING SACRIFICE, HOLY, ACCEPTABLE UNTO GOD, WHICH IS YOUR REASONABLE SERVICE.

Brethren

When you are saved you become a part of the greatest family, the family of God. you become a spiritual brother or sister with all other believers!  You will one day live with them all in heaven but there are many whom you should bond with now.  Be willing to be part of a church that will teach you the Bible and help you to walk well for the Lord. after a time you will be able to help other new believers!

Living Sacrifice

The Lord has a great plan for you!  This plan will often be opposed to the plan others have for you and even the plans you have for yourself. Be willing to sacrifice these plans for God's plan. This is what being a living sacrifice means, doing what God wants for your life rather than doing anything else.

Reasonable Service

This is reasonable.  First, Jesus Sacrificed His life for you. Second, He created you, so he knows best what you are made for. Third, He is God so he knows what is best. And Forth, He is Good, so his will is not going to be bad for you, but good.  Follow the Lord Jesus Christ.  There is no better Way for your life than where He will lead you!
