The spiritual reproductive process is not solely God's work in us, but we also play a major role in what is happening. The work of God in this world is the implantation of His Spirit in us which gives to us the barest elements of the Divine nature, and then He works on the growth and perfection of holiness in His people. We are part of a work of transformation, of conversion, to holiness.
It is here that prayer fits into the picture because Peter writes in verse 17, "and if you call on the Father." That is prayer. Prayer is an integral part of the obtaining, the achieving, the process of transformation—from the glory of man to the glory of God. Prayer fits right into the scheme of things.

What Is Prayer?
God demands that those who are associated with Him, those set apart by Him to be a dwelling place for His Spirit, be holy as He is holy. This means that we must become, not merely set apart, but set apart and clean. We are entering the area of Chrisitian conduct, and our separation is away from those who are not clean, not pure spiritually as God is.
We see the implied meaning of sanctification coming into play, because in order to be a suitable dwelling place for God, we have to become holy as He is holy. We have to become holy, then, in the sense of clean—a clean life, as well as clean in our sacrifices. I Peter 2:5 says that we are "to offer up spiritual sacrifices, acceptable to God by Jesus Christ."
We have to be holy in the sense of clean living, and our sacrifices need to be acceptable. This deals with being made holy by Jesus Christ, that is, through His work made possible by means of the blood of His sacrifice as a man, as well as His continuing work of sacrifice as our High Priest before God as our Mediator and Intercessor.

Sanctification and Holiness (Part 1)
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."
