Satan oppses all of God's servants all of the time. Some opposition comes at random intervals, some comes because of the location we live in, some comes because of our age (different for old and young), some comes because of our age in the Truth (different for new ones and experienced), and some comes for other reasons.
But generally, Satan focuses on those who serve Jehovah fully. He can cause more damage or disarry spiritually if he attacks a leader or example to the flock as compared with someon who is barely hanging on. Jehovah knows us personally. Whether you Pioneer or simply serve him "whole-souled" in whatever capacity that you can, he knows the circumstance.
If we have the ability and circumstances to serve him as a Pioneer but refuse because we are afraid...well, he knows that also. We could be afraid of the work, we could be afraid of the possibility of failure, we could be afraid of some form of persecution or trouble, God knows our fears. Don't let the fear win. The favor of God is worth much more than the fear of Satan. Remember the apostles, they all said, 'We will stick with you'. A few hours later and they had all abandoned him. Peter even verbally denied knowing him. How many times was he beaten, tortured or had a court sentence him to death? NONE...he simply allowed his mind to dwell on possible, imagined bad outcomes. It was enough, fear won (that time).
Peter and the others reganed their composure and were steadfast for the rest of their lives. They served with earnest in Jehovah's work under Christ's direction. We should try to do the same...💗
