As a monergist, I frequently spend my time speaking with synergists about this thing called "free will". They insist that we have free will. Most of the time, I have no idea what they mean by free will. Can a synergist kindly explain to me what free will is?
It appears to me; according to Scripture, that man does indeed play a part in his own salvation through having faith as seen in the following verses.

16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.

John 3:36

Romans 10:11-13
For the Scripture says, Everyone who believes in him will not be put to shame. For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. For everyone who calls on the name of the Lord will be saved.
Romans 10:8-10
But what does it say? The word is near you, in your mouth and in your heart (that is, the word of faith that we proclaim); because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved.
John 10:31
But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.

And behold, a lawyer stood up to put him to the test, saying, Teacher, what shall I do to inherit eternal life? He said to him, What is written in the Law? How do you read it? And he answered, You shall love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind, and your neighbor as yourself. And he said to him, You have answered correctly; do this, and you will live.

And because lawlessness will be increased, the love of many will grow cold. But the one who endures to the end will be saved.

Bear fruit in keeping with repentance.

Seek the Lord while he may be found; call upon him while he is near; let the wicked forsake his way, and the unrighteous man his thoughts; let him return to the Lord, that he may have compassion on him, and to our God, for he will abundantly pardon.
