Abide means to remain; to continue where you are. Now, a citizen of the Kingdom continues to obey the Lord God's Word regardless of what the world system may say. A citizen of the Kingdom is always a disciple and is forever learning the Lord Gods truth. A Kingdom citizen of good standing is always on their best behavior, meaning in line with God's Word. Always striving to do the Will of the Father.
The one who abides in the Word of God knows the truth. When you fill yourself with the Word, you become full of truth and that truth works within you to make you free. It is a process.
