Sanctification

With our lengthy sojourn in purgatory yesterday, it is worth asking how it is that we can fulfill Jesus' words,

"Therefore you are to be perfect, as your heavenly Father is perfect" (Matthew 5:48)

which themselves echo Leviticus 11:45,

"For I am the LORD who brought you up from the land of Egypt to be your God; thus you shall be holy, for I am holy."

Christians are called to a process of sanctification, which means to be made holy. This takes a lifetime and more in which we grow in grace and love as we more closely conform our lives to Jesus' life over time.
One sermon in the archives on this is called Becoming Like God. Another sermon called Pop Tarts and Pickles contrasts justification and sanctification without using fifty-cent words though that sermon is available only in audio form.
