by grace!

According to this doctrine of His they should abstain from their sins, repent, believe His promise, and entirely trust in Him; and since we cannot do this by ourselves, of our own powers, the Holy Ghost desires to work these things, namely, repentance and faith, in us through the Word and Sacraments. 72] And in order that we may attain this, persevere in it, and remain steadfast, we should implore God for His grace, which He has promised us in Holy Baptism, and, no doubt, He will impart it to us according to His promise, as He has said, Luke 11:11ff : If a son shall ask bread of any of you that is a father, will he give him a stone? Or if he ask a fish, will he for a fish give him a serpent? Or if he shall ask an egg, will he offer him a scorpion? If ye, then, being evil, know how to give good gifts unto your children, how much more shall your heavenly Father give the Holy Spirit to them that ask Him!
