Oh... forgot to mention, while apologetics and great rational arguments are important to clear up our own understanding, they do little to help others to believe.
For Christ did not send me to baptize, but to preach the gospel--not with words of human wisdom, lest the cross of Christ be emptied of its power.For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God....
Jews demand miraculous signs and Greeks look for wisdom,but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles,but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God. (1 Co 17, 22-24)
It is not our words, arguments or philosophy that has power to move people, it is God's words through His power and our submission.
Consequently, faith comes from hearing the message, and the message is heard through the word of Christ. (Ro 10:17)
