Why should others change for Christ? I do not get it. You have not even given a reasonable explanation as to why someone should change for Christ.
You can be a perfectly good person and do great and moral deeds without Christ.
So what is the justification for changing for Christ?
Oh sure I have. I've written a ton on the topic on this board and the religion board. My testimony about Jesus Christ has been shared repeatedly. Defenses of my faith spanning a number of topics have been presented and discussed, but certainly not every objection is addressed. All I can do is share honestly what I know and if I don't have an immediate answer to an objection I'll do my level best to search one out. If my testimony and faith doesn't resonate with someone it's not my responsibility to continue attempting to "convince" you.....that's pure folly. My responsiblity is to share my faith and live as a representative for Christ.
I just ask that others don't cower behind the now cliche "I'm searching for a cogent explanation and haven't found one yet" statement. The best apologetic defenses and testimonies have been callously flicked away with that canned, subjective statement. What convinces one person to pursue a relationship with Christ may not convince another, but I find that those that are "convinced" already desire to know God and are looking to understand how. If you've already decided you have no desire for anything God-related in your life then there's little else I can offer you....your choice is made. Certainly I don't prefer it, but it's not my choice to make.
In the end, we are all sinners and the only way to align ourselves with God is through the shed blood of his Son Jesus Christ. By admitting that we are sinners and accepting Christ as Lord and Savior we are then saved from his judgement by his grace through our faith and thereby justified and deemed righteous before him. Our sin debt extinguished forever by a sacrifice of love and grace. As a believer we then repent of our sin, changing our minds completely about engaging in sinful acts and striving to live according to the will of the one we claim as Savior. As believers were are indwelled (connected at the soul if you will) by his Holy Spirit that guides and demonstrates for us the reality of who he his in our lives.....God is made manifest and tangible. All I can tell you is that my life has only improved once I surrendered to will of the one that chose me first.
So what is the justification for changing for Christ? Being justifed by faith and deemed righteous and having your sin debt extinguished and thereby aligned with the one that created you. You can know the reality of God, but you have to want to first....relationships are like two-way streets.
