What makes you strong in Christ? 1 Corinthians 15-16

1 Corinthians 16:13 (NASBStr)

Be on the alert, stand firm in the faith, act like men, be strong.

In the books of Habakuk, Romans, Galatians and Hebrews each author quotes the same phrase at the hand of the Holy Spirit:  "The just shale LIVE by faith."   In this statement we have an indication of how God expects us to live our life after we are justified.  He is telling us that not only are we justified by FAITH, but our daily sanctification (living a holy life) is by FAITH.   Nothing is in the flesh.   My faith that God will justify me makes me a child of God.   My faith that God will sanctify me makes me act like a child of God.   Faith is at the beginning and throughout our walk with God.   Note what the Bible says about Faith:We can only please God by faith (Hebrews 11:6); we stand by faith (1 Corinthians 16:13); we walk by faith (2 Corinthians 5:7); we live by faith (Galatians 2:20); we fight by faith (Ephesians 6:16).   There is no work done in the flesh that will please God.   When we have faith in God He gives us the Holy Spirit.  The Holy Spirit then begins to produce fruit in our lives.   So, our ability to 'stand firm" (see above) is by faith.  Our standing is done on the knees of faith.   We can act like men because we come to God in faith as infants.   We can be strong because we are strong in faith.  Don't expect to be justified by works.  You can only be justified by faith.   Don't expect to be sanctified (be alert, stand firm, act like men) by works.   You can only be sanctified by faith.
