Often people ask this question to find out about our religious background and heritage. As if to say that it doesn’t really matter what persuasion we are or what we believe, just as long as we are sincere and make some sort of confession. Those to whom the Lord has been pleased to reveal the gospel, are fully convinced and totally persuaded of what God in His grace has been pleased to teach them from the scripture. Believers are no longer tossed to and fro and carried about with every wind of doctrine, they are committed and addicted to the truth (Eph. 4:14). Have you been fully persuaded by God the Holy Spirit? It is not presumption to believe all the precious promises of God (2 Peter 1:3). It would be presumption to believe that God is going to save wretched sinners, if He did not tell us in His Word that Christ Jesus came into the world to save sinners (Matt 9:13). Let me give two examples of believers who were fully persuaded.
Abraham did not presume to believe that God was going to give Him a son; no, he acted upon the promise of God that he would have a son. Read the record, "And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sarah's womb: He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God; and being fully persuaded that, what he had promised, he was able also to perform" (Rom. 4:19-21).
The apostle Paul was another believer who was fully persuaded. Read the record, "Whereunto I am appointed a preacher, and an apostle, and a teacher of the Gentiles. For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day" (2 Tim 1:12).
The next time someone asks you, "what persuasion are you?" Answer them with the word of truth; I am fully persuaded that God is able to perform all His pleasure. I am fully persuaded that nothing can separate us from the love of God which is in Christ Jesus our Lord (Rom. 8:35-39). I am fully persuaded that God is able to keep His sheep forever. The believers persuasion is not based upon the whims and wishes of men, but rather upon the everlasting Word of God.
