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. Romans 12:1
When we come to God, we give God our lives and we then trust Him with it. But it is completely reasonable to trust our lives with Him because he is all knowing and all sufficient. We are limited in our own knowledge but He knows everything. So there is a place of yielding to God and His way instead of by sight and doing it the way that we think it ought to be done. This takes faith. Learn in this series how to walk trusting the Holy Spirit and his direction for our lives. A life of service and worship to God which is our reasonable service.
Since, then, you have been raised with Christ, set your hearts on things above, where Christ is, seated at the right hand of God. 2 Set your minds on things above, not on earthly things. 3 For you died, and your life is now hidden with Christ in God. Colossians 3:1
Set your heart on the things above, obeying and doing the will of God. God promises that if we are willing and obedient, we will eat the good of the land. When we are born again and given eternal life, we died and are dead unto the things of this world. Learn in this series how to maintain fellowship and intimacy with God.
