Logic doesn't matter, faith matters.
Logic is an aspect of God's nature, so in what way doesn't logic matter?
I suppose apologetics has some role in Christian life, but I don't know what it is.
It is to defend the faith--"to give a defense" is the basic meaning of
apologia, and, according to Thayer's, it also means, "a reasoned statement or argument." So apologetics is that branch of theology that helps both believers and unbelievers to know that the Christian faith is rational and coherent, that it is reasonable.
1Pe 3:15 but in your hearts honor Christ the Lord as holy,
always being prepared to make a defense [
apologia]
to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect, (ESV)
Here Peter commands all believers to be prepared to engage in apologetics, "to make a defense." The following shows that Paul engaged in apologetics as a matter of custom:
Act 17:2 And Paul went in,
as was his custom, and on three Sabbath days he
reasoned with them from the Scriptures,
Act 17:3
explaining and proving that it was necessary for the Christ to suffer and to rise from the dead, and saying, “This Jesus, whom I proclaim to you, is the Christ.” (ESV)
The word
apologia isn't used, but that is precisely what Paul was doing.
Preach the Gospel let God do the convincing in people's heart.
And God can and does use apologetics to clear the way for receiving the gospel, by doing away with arguments against Christian beliefs. It is all the more necessary in a pluralistic society, and every Christian should have some level of knowledge in apologetics, in my opinion.
Everyone can be convinced that they are a sinner and that they need a Savior.
We are sowers, seed will fall on all sorts of ground. All apologetics must lead to the Gospel.
Yes, all apologetics should ultimately point to the gospel.
