"I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service." ~Rom 12:1~
My life is not my own, never has been. The choices I make do not just affect me, they affect everyone around me. Those choices either take me closer into the will of God for my life, or take me further away from His chosen path for me.
He has plans for me, very specific plans that cross paths with people who need to be ministered to- sick, hurting, lonely people that need to hear the gospel of peace, people that need to be loved. He will bring me into direct contact with lost persons, headed straight for a devil's hell if I don't share the salvation gospel of Jesus Christ with them. .. .Me.
What is my reasonable service? To give Him my life, complete control, every area, total surrender.
What if He calls me to do something I don't feel qualified to do like Moses? . . Step out in faith, knowing The I Am goes with me, strengthening me to accomplish it, & preparing my way. And if He calls me to a place I'd rather not go like Jonah? Go anyway, believing that my obedience could lead thousands to the Lord.
That, my friend, is pretty reasonable in God's eyes.
