A Christian does not work to get to Heaven but he works because he is going to Heaven.
Ephesians 2: And you hath he quickened, who were dead in trespasses and sins;
 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:
 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
We in the past looked out for number one and we were number one to ourselves.
 But God, who is rich in mercy, for his great love wherewith he loved us,
 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
 That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
We sometimes get spoiled and want want want but God has promised us our blessings will come in the future ages.
 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
 Not of works, lest any man should boast.
 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Here God reminds us it is not by anything we have done but by His grace alone we are saved. Not by our good works BUT after His grace has been bestowed upon us there becomes an expectation we will exhibit His grace and love through our works.
The purpose for which Christ made us is to exhibit His love through us towards the lost. As the Apostle Paul wrote we are ambassadors of Jesus Christ.
Titus 3: Put them in mind to be subject to principalities and powers, to obey magistrates, to be ready to every good work,
 To speak evil of no man, to be no brawlers, but gentle, shewing all meekness unto all men.
 For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.
 But after that the kindness and love of God our Saviour toward man appeared,
 Not 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;
 Which he shed on us abundantly through Jesus Christ our Saviour;
 That being justified by his grace, we should be made heirs according to the hope of eternal life.
 This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.
Too many times Christians having forgotten how rotten we were condemn the lost for being lost. They do what they do because they do not belong to God. There was a time when we were JUST LIKE THEM and it is not through some goodness within us we are now different but through the mercy of God we are different.
The word of God is clear: WE ARE NOT TO SPEAK EVILL OF ANY MAN! Rather we are to remember we were rotten sinners just as they are and we are to manifest the grace of God to them and preach to them salvation through the atoning work of Jesus Christ.
1) Our works show we belong to God. How can we convince the gainsayers we belong to God if we act like the devil?
2) If we treat our fellow man with contempt how can we tell them God loves them and desires them to be saved?
3) We manifest God’s love by the kindness we show to others.
4) We contrast the evil in the world by the good that we do.
Philippians 2: If there be therefore any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any bowels and mercies,
 Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind.
 Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves.
 Look not every man on his own things, but every man also on the things of others.
 Let this mind be in you, which was also in Christ Jesus:
 Who, being in the form of God, thought it not robbery to be equal with God:
 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
 Wherefore God also hath highly exalted him, and given him a name which is above every name:
 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
 For it is God which worketh in you both to will and to do of his good pleasure.
 Do all things without murmurings and disputings:
 That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;
 Holding forth the word of life; that I may rejoice in the day of Christ, that I have not run in vain, neither laboured in vain.
We are to focus our attention on:
The benefit of others
Jesus left Heaven to die on a cross for the benefit of mankind.
We are to manifest the fact we are saved.
Holding forth hope to a lost and dying world. Not giving up in disgust but showing the love of God and giving the hope of the gospel.
