1 Peter 1:13-16
The apostle Peter provides the practical implications of this wonderful hope. Hope can go to work for us and do wonders. God's calling and purpose are certainly wonderful, but He does not intend that they set us off on a daydream. Peter is declaring a call to arms: "Pull yourself together!" "Roll up your sleeves!" "Give hard thought and wrestle with the practical implications of salvation."
Remember that the church is the community where God's truth is taken seriously, and His mind is being formed in its members. To paraphrase and expand, Peter is saying, "Look, brothers, we should not be superficial about this. Keep cool. Do not be impetuous. Avoid excesses. Live a plain life. Work hard, but set your hope in God's grace, not in your own willpower.
"Remember always that your obedience is to a gracious Person, not to a coldly calculating judge or to society. Holiness is not sanctimoniousness. It is being separated for a special purpose by special instructions and discipline. We have been called to perform a unique purpose. We have been called to glorify God by our lives as a witness to all who observe, and at the same time being prepared for His Kingdom. God wants us to have a passionate love for goodness, so in your mind give Him a unique place.
"Do not fear the enemy, as we would Christ. Use your hope to think about Him, His power, justice, wisdom, goodness, truth, omnipotence, and omniscience. Remember always that He has wisdom without error, power without limit, love without hatred. Our hope is in One who is great in every respect. Quit thinking of God in fleshly terms. He is not a limited man nor even a superman. He is GOD! He is with us, and so who can permanently harm us? Concentrate on being completely devoted to Him, and if we do this, we have every reason to hope. God is not a man that He should lie. His promises are sure."
