Paul, called by the will of God to be an apostle of Christ Jesus, and our brother Sosthenes, To the church of God that is in Corinth, to those sanctified in Christ Jesus, called to be saints together with all those who in every place call upon the name of our Lord Jesus Christ, both their Lord and ours(1 Cor1:1-2).From Paul's salutation to the church in Corinth, we learn a vital truth: He was " called by the will of God"(vs1) and this is true of every believer; we are also "called by the will of God": "called to be saints together with all those who in every place call upon the name of our Lord Jesus"(vs 2 see also Rom 8:29-30, Joh 1:12-13 ).
Why are we called? We are called to be reconciled to God from sin. We are called to be transferred from the kingdom of darkness into the Kingdom of God. We are called to become children of God (John 1:12-13), set apart for His use Holy use: "sanctified in Christ Jesus" God's call was made before the foundations of the earth and we contributed nothing to it. If you are a believer, you were set apart as a chosen vessel to reveal His glory and be conformed to the image of Christ (Romans 8:29, 9:23).
Paul was called by the will of God to be an apostle. The believers in the church of Corinth were also called. God's calling is in no relation to any inherent good in us. Our calling is rooted in God's mercy and His grace (Eph. 2:1-10 ). Remember Paul was a persecutor of the church of His day, before his encounter with Jesus.
Like Paul and the Corinthian believers; every believer is called with an assignment to fulfill. We are not on a "self-sent" assignment on earth. Our lives, our breath, our purpose for existence all takes its source from God. "In Him we live, move and have our being"(Acts 17:28). We are all on God's assignment. He brought us on earth for His purpose, His will, His plan and His agenda. Our life originates and evolves around God and what He created us for.
If there is any truth that will sustain us, it is that we take our existence from God. We are, because He is: self-existent and all sufficient. We take our sufficiency from Him. We are complete in Him (Colossians 2:10 ) and without Him, we can do nothing (John 15:5 ). God Is Our source of Existence. The Bible opens with the words "In the beginning God..."(Genesis 1:1).Our lives and the whole of the Universe takes its source from God(Rev. 4:11, John 1:3-4)
