I can do all things through Christ, who strengthens me. - Phil 4:13
As humans, we cannot prevent fear from passing through our minds but we can resist it from pitching it's tent in our hearts. So if you must get going like clockwork in life, you need to be courageous. Those who pull out all the stops to their advancement in life don't allow fear to dictate their resolutions and decisions. They don't drop the ball but keep it rolling even when it appears that the odds are against them to succeed.
Essentially, courage helps you to leverage the grace of God to press forward when others are bailing out. It helps you to pursue your goal in life even when it appears that oppositions against you will have the upper hand. It took courage for Moses to confront the Red Sea. It also took courage for Joshua to take on the leadership mantle. And we could also see from the scripture that courage was the force that helped Esther to breakthrough limits.
Hence, don't undermine your ability to take the bull by the horn. So whenever you are confronted with situations or challenges that seem to be beyond you, get your act together and leverage wise counsel, divine inspiration and God's grace so you don't get overwhelmed with fear. Of course, courage helps you to keep all resistance to your success and accomplishments at bay. May you never get frustrated out of the pursuit of your dreams, goals and aspirations as you put up a bold front henceforth in Jesus name.
