We have not chosen God, He has chosen us (John 15:16). It is God Who wills in us to do His good pleasure (Phillipians 2:13). It is God Who gives to every man his measure of faith (Romans 12:3). It is God Who orders the thoughts of a righteous man (Proverbs 16:3). The steps of a good man are ordered by the Lord (Psalm 37:23). The Holy Spirit gives gifts to men as He chooses (I Corinthians 12:11). God has mercy on whom He chooses to have mercy (Romans 9:15).
Anything and everything that a Christian might accomplish is by grace, and God's Holy Spirit. It is not of works that any should boast.
No one should inflate themselves, have confidence in self, or think highly of himself. All of this is pride and pride blinds us to the truth. When the blind lead the blind, they both fall into the ditch (Luke 6:39).
Be wary of following men, the doctrines of men and denominations. There is but one role model, the lord Jesus Christ. The Holy Spirit will lead each of us into all truth.
All men have clay feet.
