Hello Akita, we are called to be His
witnesses, and to
preach the Gospel to all .. e.g.
Mark 16:15; Acts 1:8, so you are correct that our witnessing to others (of that which we have personally experienced, both of the Lord and of our newfound faith) must come from the heart, as it does require vulnerability and love to be effective .. e.g.
1 Corinthians 13:1 (and compassion for the state of the lost), but at some point (with or w/o "logic"), the Scriptures themselves play a BIG part in all of this (witnessing, evangelism and/or apologetics, that is).
As the Apostle tells us,
Romans 10
13 “WHOEVER WILL CALL ON THE NAME OF THE LORD WILL BE SAVED.”
14 How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher?
17 So, faith comes from hearing, and hearing by the word of Christ.
God bless you!!

p.s. - the famous quote that St. Francis is credited with saying (the one that he never actually said or lived out .. see
What St. Francis of Assisi Didn’t Actually Say from the
National Catholic Register) was restated (or perhaps better, corrected) by theologian Ligon Duncan with these words: "
Saying, preach the Gospel daily, use words if necessary, is like saying, feed the hungry daily, use food if necessary"
Granted, "acting" like Christians is required of us (and should be considered a given, since it is commanded .. e.g.
Matthew 7:12), but ~speaking~ as a Christian, especially the words of Christ, is also necessary according to the Bible, ESPECIALLY in the cases of witnessing, evangelism and/or apologetics, yes?
