Firstly the scriptures read . John 15:16(KJV) Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you..
So its clear the believer didnt find Jesus but rather Jesus found the believer .
God divides children according to scriptures obedient and disobedient . obedient are children of God , disobedient children their father the devil .Ephesians 2:2(KJV) Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
The covenant ,Abraham believed God and was obedient so God counted it righteousness . Genesis 15:6(KJV) And he believed in the LORD; and he counted it to him for righteousness.
