Well…yes! That is… if one wants to be part of His Family in Christ. Paul taught us about the powers given by Satan over this flesh world, about a ‘battle’:

The whole reason we are born of woman in this flesh is to make a ‘choice’ of who we will serve, whether that be Christ our Lord, or defaulting to Satan, the controller of ‘this’ world (Luke 4:1-8). There is NO in between! There is no ‘my’ side, or ‘our’ side of neutrality. What did our Lord Christ say to the Church of Laodicia about spewing them out of His mouth, because they were neither ‘hot’ nor ‘cold’, but ‘lukewarm’ (Rev.3:16). Our Lord is teaching there to ‘choose’. Pick which side you want to be on; make up your mind. Those who make no choice, naturally ‘default’ to Satan’s side, regardless of whether they like it or not. The false teaching that each one can be their own ‘individualist’ just won’t work in this matter with our LORD. Choose.

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.
14    Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15    And your feet shod with the preparation of the gospel of peace; 16    Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
17    And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
18    Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;

Notice Eph.6:13 above says to “take” ‘the whole armour of God’. Does that mean by only believing on Christ Jesus as our Savior, that we will just be given God’s Armour, with no work? No…we must “take” It. We must spiritually ‘eat’ The Book, His Word, taking It into our minds and hearts (see also Rev.10:9-10).
Being Christ’s servants means doing work for Him, according to His Will. ‘Works’ are very important to being ‘in Christ’. We are not saved by our ‘works’, but by ‘grace’, a ‘gift’ which we did not merit, a Precious Gift from our Lord and Savior. But… our ‘works’ do follow us to Heaven, for they are our just rewards. We will be judged by our ‘works’ (Rev.14:12; Rev.20:12-13; Rev.18:6). A good ‘work’ for Christ can be something as simple as a smile to comfort a brother/sister who is depressed, etc. So ‘works’ do not necessarily mean going out and becoming an El Cid (though God does send those).
Is it any different than joining up to play school sports? Do we go through weeks of training just to sit down or throw it all away when game time comes along? Of course not. It’s no different with God’s servants. This life is our ‘game’ Which we enjoy, because we have a Perfect Winning Strategy from the Best COACH (Christ Jesus) in the league, so we naturally would want to get out there and sweat a little, getting ourselves ‘in shape’, so we can be part of HIS TEAM! And what A COACH we have in Him! A Perfect Coach! Likewise, those who want to serve God have to learn how to run the ‘playbook’ (Bible), having It locked away in the heart and mind. One may begin on the fourth string, but working hard, they’ll soon be first string starters in doing His ‘work’. And when God’s Team wins, all His Body of members win together, as we all have the same inheritance in Christ (Eph.3:6; Gal.3:7-9; Romans 12; 10:12-15; Acts 20:32). And… we already ‘know’ Who wins.
