verse 22> strengthening and establishing the hearts of the disciples; encouraging them to remain firm in the faith, saying, “It is through many tribulations and hardships that we must enter the kingdom of God.”

What I have seen here is that Christianity is not a bed of roses ,for the fact that you are a Christian doesn't mean you will not pass-through tribulation, we can see here that Paul encourages the disciples that they should stand firm despite the huddles and that before you enter into the kingdom of God you must pass through tribulations (remember pass through many tribulations) that means not just one tribulation but many, so it's possible that you lost a Job and a love one the same day or month or year.

May God help us never to abandon him in this hard times.

Thanks so much for sharing @reliquary
