'Hardships' in the Bible

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.”

But [like a boxer] I strictly discipline my body and make it my slave, so that, after I have preached [the gospel] to others, I myself will not somehow be disqualified [as unfit for service].

but we commend ourselves in every way as servants of God: in great endurance, in sufferings, in hardships, in distresses,

So I am well pleased with weaknesses, with insults, with distresses, with persecutions, and with difficulties, for the sake of Christ; for when I am weak [in human strength], then I am strong [truly able, truly powerful, truly drawing from God’s strength].

Take with me your share of hardship [passing through the difficulties which you are called to endure], like a good soldier of Christ Jesus.

because he preferred to endure the hardship of the people of God rather than to enjoy the passing pleasures of sin.
