Herein is my Father glorified, that ye bear much fruit; every tree therefore which bringeth not forth good fruit is hewn down, and cast into the fire. Joh 15:8 Luk 3:9
If you are truly saved, it will be your desire to bring honor to God. As it is a honor to a husbandman to have strong branches laden with much fruit, so God is honored by having holy, victorious, sin-free, purified, children that live a life of self denial, are growing spiritually, and are full of the fruit of the Spirit.
Likewise, we give much heed to the warning that God is expecting fruit from His children. Those that will not abide in Christ through obedience, nor have his faith producing Word in them will not bring forth fruit. These will be gathered up and cast into the fire. Let us all be moved with fear and give heed to the Word of God on fruit bearing.
In order to bring forth fruit you need to be saved from sinning and in order to bring forth much fruit you must be restored to the divine image.
Salvation from Sinning — God is honored when a person is converted from the kingdom of darkness into the kingdom of his Son (Col 1:13) and set free, not only from the guilt and penalty of sin, but from the power of sin. Those that teach that salvation doesn’t deliver from the power of sin, to the degree that a new Christian is free from the spirit of disobedience (Eph 2:2), err not knowing either the scriptures nor the power of God (Mat 22:29).
God is not only able to save people from the power of their sins (Mat 1:21), but he is able to keep them from going back to their sinning (1Cor 10:13, 2The 3:3, 2Pet 1:10, Jud 1:24). For further reading see the article on what true conversion is.
Restored to the Divine Image — After you are saved from the power of committing sin by the new birth, there is the baptism of the Holy Spirit that saves from the pollution of sin. This baptism of fire purifies the heart (Act 15:9) and is received by asking in faith (Luk 11:13). When you are saved, your sins are forgiven (1Joh 2:12) and are completely taken away (1Joh 3:5). You no longer commit sin (1Joh 3:9), but while you have power over sinning there still remains that sin nature in the heart (Rom 7:17, 20) which must be suppressed. This is what is removed when your heart is purified (Act 15:9) though the baptism of fire (Mat 3:11).
This is the restoring of the image that God originally made man in (Gen 1:26) which is righteousness and true holiness (Eph 4:24). For further reading see the article on what promise of the Holy Spirit is and what the promise of the Holy Spirit does.
