My friend, your election is first demonstrated by "Your work of faith". All should see that "you are turned to God from idols to serve the living and true God."
Works don’t lie!
Jesus said I know thy works, and in Revelation 2:23 he says, "and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works."
Serving the Lord, is wholeheartedly following him. And our calling is that us or yourself that you should lay an example for all that believe, by "your work of faith, and labour of love, and patience of hope" that you believe in God. Paul said, "from you sounded out the word of the Lord...in every place your faith to God-ward is spread abroad; so that we need not to speak any thing" 1 Thessalonians 1:8. I like it when my pastor visits me and he needs not to speak any thing. It means all is well!
"Knowing, brethren beloved, your election of God. For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake." 1 Thessalonians 1:4-5.
Ask yourself also, what manner of a christian am I? Am I a good example? Do my works demonstrate that I’m elect of God to others?
Know how God has chosen you, and how that he given you his word. That word he gave you should not just be a meaningless chatter to you, but life. It should through the Holy Ghost produce a powerful effect in you, and in much assurance.
