What the Holy Bible says about Purpose:

28 And we know that in all things God works for the good of those who love him, who have been called according to his purpose. (Romans 8: 28)

12 Don’t let anyone look down on you because you are young, but set an example for the believers in speech, in conduct, in love, in faith and in purity. (1 Timothy 4: 12)

21 Many are the plans in a person’s heart, but it is the Lord’s purpose that prevails. (Proverbs 19: 21)

Therefore if you have any encouragement from being united with Christ, if any comfort from his love, if any common sharing in the Spirit, if any tenderness and compassion, then make my joy complete by being like-minded, having the same love, being one in spirit and of one mind. Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others. In your relationships with one another, have the same mindset as Christ Jesus. (Philippians 2: 1-5)
