Phil. 1:27-28 - However comma

27 Only conduct yourselves in a manner worthy of the gospel of Christ, so that whether I come and see you or remain absent, I will hear of you that you are standing firm in one spirit, with one mind striving together for the faith of the gospel;
28 in no way alarmed by your opponents--which is a sign of destruction for them, but of salvation for you, and that too, from God.

Don’t Be Alarmed

Paul expressed confidence in the Philippians in the previous verses. He was willing give up heaven for the time being - not permanently, mind you - in order to care for them, pray for them, disciple them so they would know and experience Christ as did Paul. Yet he worried for them since he was not there with them.

Vs. 27 - “Only conduct yourselves in a manner worthy of the gospel of Christ, so that whether I come and see you or remain absent, I will hear of you that you are standing firm in one spirit, with one mind striving together for the faith of the gospel”

“Only” - Nevertheless, whether I am there or not, be worthy of the price paid! Always.

“I will hear of you that...” - If Paul comes to them, (he may not if the Roman emperor doesn’t free him) they can rejoice with him in person. If Paul is detained by Rome, then he will rejoice when he hears they are not drifting from the Gospel. He will hear from messengers an witnesses they are holding to the truth.

“Standing firm in one spirit, with one mind” - When we are ALL focused on Christ as Lord and Savior, we can hold each other accountable. We are in a spiritual battle. Christian soldiers in a war against the forces of Satan. (See: Eph. 6:12-17)
The people of Philippi would clearly understand the military implications of standing firm. Warfare in the first century was very up-close and personal, i.e., mostly hand-to-hand. The foot soldiers stood shoulder to shoulder, shield in one hand, sword in the other. They had to stand firm agains the charge of the enemy, to keep them from breaking through. No army wants the enemy at their defenseless backs.
The one spirit we have is the Holy Spirit. The one mind comes from correctly understanding our salvation and spiritual growth. The Holy Spirit also will teach and lead us to the truth . When we grow in knowledge and understanding we all come closer and closer to the true path.

As an example, when a pilot is learning to fly a plane he doesn't have the knowledge or acquired skill to keep the plane on the correct glide path. The plane will drift above and below the path until the pilot gets familiar with the controls and their effects are various airspeeds. A student pilot may operate the plane when flying well above the ground. As they begin to touch down, the teacher, or senior pilot takes the yoke to steady the plane and bring it down smoothly. Similarly, when a teenager is learning to drive a car, the first goal is to learn to keep the car in the lane. All these skills, braking, steering, parking, etc., must be learne and practiced until they become habits.

Vs. 28 - “in no way alarmed by your opponents--which is a sign of destruction for them, but of salvation for you, and that too, from God.”

“in no way alarmed by your opponents” - You, the church, will never be without opponents (at least while the church is on this earth). Don’t worry when enemies of Christ try to bring down the church. This will happen until the end of time. Remain strong and true in the faith. Your stability, your strength, your peace in Christ will only serve to show the enemies how they are losing the battle.
