What do you think the bible says?
If you are asking what they are asking below... then...
John 6:28Then said they unto him, What shall we do, that we might work the works of God? 29Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
Believe in Jesus for salvation and to help you live as His thus the just shall live by faith.
If you are asking how Jesus would have us live as His... it is not by keeping the commandments of the law but leaning on Jesus to do the spirit of the law and that is to love one another... even our enemies.
Romans 13:7Render therefore to all their dues: tribute to whom tribute is due; custom to whom custom; fear to whom fear; honour to whom honour. 8Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. 9For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. 10Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
So in a nutshell, the life of a believer in Christ Jesus can be summed up under these two commandments alone.
1 John 3: 22And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight. 23And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment. 24And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.
Now as for external works.. things that are in our power to do as opportunities arises... to show love for one another....as well as towards God...
James 1:27Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.
But do consider this...
Romans 4:5But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. 6Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,
We serve Him as He enables us as we love others as He enables us, but if no opportunities has arisen, we rest in Jesus that we are His as it is His righteousness that brings us Home.
Titus 3: 4But after that the kindness and love of God our Saviour toward man appeared, 5Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; 6Which he shed on us abundantly through Jesus Christ our Saviour;
