2 Corinthians 6:4 but as servants of God we commend ourselves in every way: by great endurance, in afflictions, hardships, calamities, beatings, imprisonments, riots, labors, sleepless nights, hunger; by purity, knowledge, patience, kindness, the Holy Spirit, genuine love; by truthful speech, and the power of God; with the weapons of righteousness for the right hand and for the left
Romans 14:18 Whoever thus serves Christ is acceptable to God and approved by men.
1 Thessalonians 2:3-11 For our appeal does not spring from error or impurity or any attempt to deceive, but just as we have been approved by God to be entrusted with the gospel, so we speak, not to please man, but to please God who tests our hearts.
Romans 5:3-4 Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope,
Colossians 1:11 being strengthened with all power, according to his glorious might, for all endurance and patience with joy
Hebrews 12:1 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,
James 5:7-10 Be patient, therefore, brothers, until the coming of the Lord. See how the farmer waits for the precious fruit of the earth, being patient about it, until it receives the early and the late rains. You also, be patient. Establish your hearts, for the coming of the Lord is at hand.
Revelation 3:10 Because you have kept my word about patient endurance, I will keep you from the hour of trial that is coming on the whole world, to try those who dwell on the earth.
We often think of patience as a passive thing – the ability to sit around and wait for something to happen. That is not the idea of the word Paul used here. It is an active endurance instead of a passive waiting. The ancient Greek word hupomone “does not describe the frame of mind which can sit down with folded hands and bowed head and let a torrent of troubles sweep over it in passive resignation. It describes the ability to bear things in such a triumphant way that it transfigures them.” (Barclay)
“Nowadays it is not the violence but the mockery or the amused contempt of the crowd against which the Christian must stand fast.” (Barclay)
Paul knew he needed endurance, and he knew many things in his life drew him to seek that endurance. Some of them were the general trials of life, some were sufferings directly brought by others, and some were self-inflicted. Not every trial was the same, but they all made him need endurance.
The idea of on the right hand and on the left is of holding both offensive and defensive weapons. It probably has in mind “both advancing and being attacked.” “Particularly, the shield and the sword; the former on the left arm, the latter on the right hand. We have the doctrine of truth, and the power of God, as an armour to protect us on all sides, every where, and on all occasions.” (Clarke)
