Philippians 2: 23-24….. I hope therefore to send him just as soon as I see how it will go with me, and I trust in the Lord that shortly I myself will come also.
Alec Motyer says,
“Paul’s doctrine taught him that a sovereign God ruled all things: whether freedom or imprisonment, comfort or discomfort, sickness or health. The child of God lives under the sovereignty of God. Paul’s practice was to accept without question or rebellion what the Lord ordained. The same Lord who called him to be an apostle could and would also ordain the sphere of apostleship, be it a free-roving commission to the Gentile world, or the restrictive limit of a Roman gaol”
(J.A.Motyer, “The Richness of Christ,” IVF, London, 1966, p.102).
Paul was aware of and submitted to Almighty God as we see in Philippians 2. His trust was in the sovereignty of God.
