Counted worthy

The phrase, or idea, of being counted worthy of being a follower of Christ occurs a few times in the New Testament. Some of these times are related to suffering for Christ's sake. All of them are related to being faithful. Here they are (all quoted from the public domain World English Bible):

Matthew 10:37 He who loves father or mother more than me is not worthy of me; and he who loves son or daughter more than me isn’t worthy of me. 38 He who doesn’t take his cross and follow after me, isn’t worthy of me.

Acts 5:40b Summoning the apostles, they beat them and commanded them not to speak in the name of Jesus, and let them go. 41 They therefore departed from the presence of the council, rejoicing that they were counted worthy to suffer dishonor for Jesus’ name

Ephesians 4:1 I therefore, the prisoner in the Lord, beg you to walk worthily of the calling with which you were called, 2 with all lowliness and humility, with patience, bearing with one another in love; 3 being eager to keep the unity of the Spirit in the bond of peace. 

Philippians 1:27 Only let your way of life be worthy of the Good News of Christ, that, whether I come and see you or am absent, I may hear of your state, that you stand firm in one spirit, with one soul striving for the faith of the Good News; 28 and in nothing frightened by the adversaries, which is for them a proof of destruction, but to you of salvation, and that from God. 29 Because it has been granted to you on behalf of Christ, not only to believe in him, but also to suffer on his behalf, 30 having the same conflict which you saw in me, and now hear is in me

Colossians 1:9 For this cause, we also, since the day we heard this, don’t cease praying and making requests for you, that you may be filled with the knowledge of his will in all spiritual wisdom and understanding, 10 that you may walk worthily of the Lord, to please him in all respects, bearing fruit in every good work, and increasing in the knowledge of God; 11 strengthened with all power, according to the might of his glory, for all endurance and perseverance with joy;

1 Thessalonians 2:11 As you know, we exhorted, comforted, and implored every one of you, as a father does his own children, 12 to the end that you should walk worthily of God, who calls you into his own Kingdom and glory

2 Thessalonians 1:3 We are bound to always give thanks to God for you, brothers, even as it is appropriate, because your faith grows exceedingly, and the love of each and every one of you towards one another abounds; 4 so that we ourselves boast about you in the assemblies of God for your patience and faith in all your persecutions and in the afflictions which you endure. 5 This is an obvious sign of the righteous judgment of God, to the end that you may be counted worthy of the Kingdom of God, for which you also suffer.
11 To this end we also pray always for you, that our God may count you worthy of your calling, and fulfill every desire of goodness and work of faith, with power; 12 that the name of our Lord Jesus may be glorified in you, and you in him, according to the grace of our God and the Lord Jesus Christ.
