Do not offer any part of yourself to sin as an instrument of wickedness, but rather offer yourselves to God as those who have been brought from death to life; and offer every part of yourself to him as an instrument of righteousness.
You have a new identity in Christ. You are no longer a slave to sin and because you’ve been set free from sin you can offer yourself to God so he can use you for his purpose. Devote yourself to God and to his service with all your heart.
Can any one of you by worrying add a single hour to your life?
Worrying doesn’t change a thing and it sure doesn’t add any benefit to your life. Instead of worrying start serving. Spend time helping those in need and you’ll have less time to spend worrying. Focus on helping others and God will make sure you are taken of.
Then I heard the voice of the Lord saying, “Whom shall I send? And who will go for us?” And I said, “Here am I. Send me!”
If your desire is for God to use you, first you need to experience a relationship with him, get to know him, and recognize his voice. Second, you need to offer yourself to him through obedience and service.
