“There is one body, and one Spirit, even as ye are called in one hope of your calling; One Lord, one faith, one baptism, One God and Father of all, who is above all, and through all, and in you all” (Ephesians 4:4-6).
In Ephesians 4:6, three characteristics of the “one God and Father” are revealed. First, He is the Father “of all,” including Jews and Gentiles (Romans 3:29-30). Second, He is “above all.” Jesus taught that the Father is “in heaven” (Matthew 6:9; 23:9), and Isaiah showed how He “sits upon the circle of the earth” (Isaiah 40:22). Third, He is “through all, and in you all.” A similar statement in 1 Corinthians 8:6 indicates that God possesses this characteristic because He is the Creator of everything: “But to us, there is but one God, the Father, of whom are all things, and we in him.”
We can know that God exists by observing the various objects He has created. According to Psalm 19:1-6, the objects in the heavens declare a message that any person can hear, regardless of his language. This universal message is that God created these heavenly bodies. The evidence for God’s existence is so overwhelming that David said, “The fool has said in his heart, There is no God” (Psalm 14:1).
To know about God’s nature, His will, and the blessings He provides, we must turn to His revealed Word. To illustrate, in the 23rd Psalm, David listed twelve special blessings he enjoyed due to knowing God as his shepherd. Also, in Ecclesiastes 12:13-14, Solomon showed how fearing God and keeping His commandments are of utmost importance because everyone will face God in judgment one day. Furthermore, in Acts 17:22-31, Paul taught that there is one true God, that He cannot be compared to any image, and that He requires everyone to repent. Finally, Jesus revealed how God feels when a sinner repents (Luke 15:7, 10, 20-24).
The “one faith” teaches that the “one God and Father” wants you to believe that the “one Lord” is His only begotten Son, and He wants you to submit to the “one baptism.” If you will do so, the Lord will add you to His “one body,” you will have the “one hope” of eternal life, and you will gain access to the blessings provided by the “one Spirit.”
