While we are primarily blessed with all spiritual blessings in the heavenlies (Eph. 1:3), God has also blessed us with physical things. The Bible that you hold in your hand is a physical book with a spiritual message.
When we observe the Lord’s Supper, we are partaking of physical elements, the bread and the cup, which convey a spiritual message (I Cor. 11:23-26).
“For every creature of God is good, and nothing to be refused, if it be received with thanksgiving: For it is sanctified by the Word of God and prayer” (I Tim. 4:4,5).
The very food we eat everyday would also be classified a physical blessing. Notice that “every creature of God is good”; that is, every piece of beef, chicken, pork, fish or shellfish we eat is good and not to be withheld as unclean today. Under grace, eating a ham sandwich is acceptable. Paul adds that it is set apart by God in accordance with His Word and prayer, a clear indication that we are to offer thanks to the Lord for what we have at every meal.
The apostle instructed Timothy, “having food and raiment let us be therewith content” (I Tim. 6:8). While we are clothed spiritually in Christ’s righteousness, I wouldn’t advise leaving home physically unclothed. Our very clothing is a physical blessing.
In the context of prayer, Paul prayed that he might have the Lord’s prospering on his physical journey to visit the saints at Rome (Rom. 1:9,10). “In everything [not just some things and not just spiritual things] give thanks: for this is the will of God in Christ Jesus concerning you” (I Thes. 5:18). source
