What makes an effective Christian leader today?
Is it charisma? Is it ability? Is it communication and oratory skills?
God's view of an effective leader has nothing to do with these qualities. They may be a part of an effective leader.
However, the core attribute of a Christian leader is his integrity with God and his obedience to follow Him. When this happens, God manifests His power in and through that leader.
Moses was effective because he was willing to obey the commands God gave him. When Moses did this, God manifested His presence in him. The result was that people followed. They followed because they saw God working in and through the man. They saw that this man was worthy of following because God's anointing was on him.
When people see the Lord's power manifested in your life, they will have a healthy fear of the Lord.
They will look at you and say, "This person has something I don't have that is worthy of more investigation."
Your challenge is to seek the Lord with a whole heart, resulting in God's power being manifested in the daily activities of your life. When this happens, you can expect others to be drawn to what they see in you.
The problem with many Christians today is that non-Christians see nothing different about the way they live to motivate the unsaved to desire their faith.
What makes you different from your neighbor?
Is your experience with God noticeably different from that of the man next door?
If you're not experiencing regular encounters with God, it's time to ask why not.
We don't live day-to-day for the next spiritual experience, but we should see by-products of a life centered in God that is reflected in fruit from His presence in our lives.
