A quote from Elisabeth Elliot in A Light for My Path:
Once we have set ourselves to be pilgrims and strangers on the earth, which is what Christians are meant to be, it is incongruous for us to continue to insist upon the sort of security the world tries to guarantee. Our security lies not in protecting ourselves from suffering, but in putting ourselves fully into the hands of God. The desire for physical and material security makes us sly and hard. No. We must be like little children. The child in its father's arms is not worried. It lies quietly at rest because it trusts its father.
We disobey sometimes because we say it is impossible to do what God asks. Impossible? Perhaps what we mean is impossible to do that and keep our security, impossible to obey without tremendous cost, or at least tremendous risk. Where, then, will we find safety? Is it likely that we will find it elsewhere than in the arms of the Father?
Prayer: Teach me to rest in your everlasting arms. Make me know that all other security is illusion.
