Fasting is not about you
Everything that God did in the Old Testament and especially the New Testament was given to man to answer specific problems related to sin in the flesh. On the flip side of things, Satan, being the prince of this world has created systems to address the righteousness of God in us. You are called by God in his world with a mission to allow the Holy Ghost to teach you how to be obedient and to bring forth (results) fruit or works that please God.
Eph 6:11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
Eph 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
Eph 6:13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
Eph 6:14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
Eph 6:15 And your feet shod with the preparation of the gospel of peace;
Eph 6:16 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
Eph 6:17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
Eph 6:18 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
You will not be wrestling against flesh and blood. You will be fighting against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
The systems in which you were born to will not let you change. You must be prepared by arming yourself with the anointing of the Holy Ghost (the anointing will break the yoke) so that you can get as close 100% of fruit bearing.
2Pe 1:3 According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:
2Pe 1:4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
2Pe 1:5 And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;
2Pe 1:6 And to knowledge temperance; and to temperance patience; and to patience godliness;
2Pe 1:7 And to godliness brotherly kindness; and to brotherly kindness charity.
2Pe 1:8 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.
2Pe 1:9 But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins.
