“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).
Someone has well stated that this verse is not a question of ability, but of availability.
There is an old saying, “Where there’s a will, there’s a way.” But let’s put a little different spin on it: “When it’s God’s will, He makes a way.”
Sometimes we may question whether we have the ability or the strength to do this or that. But it is not so much a matter of “Can I do this?” but a matter of “Is it God’s will for me to do it?” If we are available and sensitive to His leading, then He will provide everything that is needed for the task at hand. His promise is, “Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee; yea, I will help thee; yea, I will uphold thee with the right hand of My righteousness” (Isaiah 41:10). Don’t be afraid to go wherever the will of God leads you or to do whatever task the will of God gives you to do.
