And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;And to knowledge temperance; and to temperance patience; and to patience godliness; And to godliness brotherly kindness; and to brotherly kindness charity.
Our part in being saved and producing fruit of the Spirit, is to add to our faith in Christ.
For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.
We must add these things to produce the fruit of the Spirit while knowing and abiding with Jesus. It has nothing to do with hard work, but only necessary working of faith hand in hand with the Spirit and Jesus Christ.
But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins.
Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall.
We do our part to produce fruit of the Spirit, or we remain blind without a sure calling and election. No surprise that those who speak of having faith alone, are also the ones always talking about falling.
For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.
We do not even enter into God's kingdom, until we do our part in adding to our faith in Him the spiritual work of virtue, knowledge, temperance, patience, godly living, loving the brethren and charity towards our neighbors.
Faith with these works is the only faith that saves and produces fruit of the Spirit within and outwardly. Faith alone without these works saves no man, being alone and dead and barren and unfruitful.
The natural minded Christian that thinks spiritual fruit is produced naturally, is only doing what comes natural, and does no spiritual work to ensure it. The live by the feelings of faith alone. They only do what they feel like doing at the time.
