Topic: I John 3:18-24
"And how can we be sure that we belong to Him? By looking within ourselves: are we really trying to do what He wants us to? Someone may say, 'I am a Christian; I am on my way to heaven; I belong to Christ.' But if he doesn't do what Christ tells him to do, he is a liar. But those who do what Christ tells them to will learn to love God more and more. That is the way to know whether or not you are a Christian. Anyone who says He is a Christian should live as Christ did" (1 John 2:3-6).
I frequently counsel with people who assure me that they are Christians, but their life-styles betray their profession. In fact, Jesus refers to this kind of person in His parable of the wheat and tares (Matthew 13:24-30).
"I never knew you; depart from me," He will say to people whose profession of Christian faith is insincere (Matthew 7:23, NAS). According to the Word of God, these people are confused, and we do them a great injustice if we do not hold before them the mirror of God's Word. Our Scripture portion today is one of the most effective passages to help open their eyes.
If there has not been a difference in your life-style since you professed faith in Christ; if, even in your failure and sin - and we all fail and sin at times - you do not have a desire to obey God and live a life pleasing to Him, it is quite possible that the new birth has not taken place in your life. Test yourself if you are not sure; if you have not done so, you can experience the new birth simply by receiving Christ into your heart today. This applies more directly to carnal Christians.
To be absolutely certain of my relationship with Jesus Christ, I will take spiritual inventory of my life and seek to ascertain whether my life-style is consistent with that of the true believer and follower of Christ.
