"Fight the good fight of the faith. Take hold of the eternal life to which you were called." Faith is a fight, no a battle, no a war. You have to fight for the faith and sometimes people get hurt; sometimes people get killed (see Hebrews 11). But it is a fight we should engage in, we must engage in because it's a fight worth having--it's a good fight. Fight to stay faithful to God and in so doing, take hold of eternal life--grasp on to eternal life and don't let go. Fighting for the faith is a matter of fleeing from sin and vigorously pursuing godliness. You are fighting for faith in the One Who holds eternal life,
"who is the blessed and only Sovereign, the King of kings and Lord of lords, who alone has immortality" (vs 15). Contend for the faith because its end is eternal life with God,
"who gives life to all things" (vs. 13).
