Like the flesh of a little child.
The miracles happen if you listen to the word of God carefully. If you follow the orders which the Scriptures give you. Further, if you are obedient and pay attention to the people who are sent by God. Thus, your spirit gets healthy and you are ready to fulfill all the precepts of God. In addition, you become thankful and acknowledge that God is a giver of all good things. Also you want to praise him and testify to his wondrous deeds. For you have experienced his kindness and faithfulness toward you. You are even ready to suffer for the Gospel as you know that this saying is trustworthy. In all circumstances you raise your voice to the Lord and ask for his mercy. Since you are aware of your weaknesses and sins. As a result, you are being cleansed by the divine grace and the power of the Holy Spirit. In such a way, you are born again as a beloved child of the heavenly Father.
