Revelation 2:1-5 (ESV)
1 “To the angel of the church in Ephesus write: ‘The words of him who holds the seven stars in his right hand, who walks among the seven golden lampstands.
2 “‘I know your works, your toil and your patient endurance, and how you cannot bear with those who are evil, but have tested those who call themselves apostles and are not, and found them to be false. 3 I know you are enduring patiently and bearing up for my name’s sake, and you have not grown weary. 4 But I have this against you, that you have abandoned the love you had at first. 5 Remember therefore from where you have fallen; repent, and do the works you did at first. If not, I will come to you and remove your lampstand from its place, unless you repent.
Hebrews 12:1-2 (ESV)
1 Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, 2 looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God.
