“But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons, ¶In pointing out these things to the brothers, you will be a good servant of Christ Jesus, being nourished on the words of the faith and of the sound doctrine which you have been following. But refuse godless myths fit only for old women. On the other hand, train yourself for the purpose of godliness, Do not neglect the gift within you, which was given to you through prophetic utterance with the laying on of hands by the council of elders. Take pains with these things; be absorbed in them, so that your progress will be evident to all.” 1 Timothy 4:1, 6-7, 14-15 LSB  https://bible.com/bible/3345/1ti.4.1-14.LSB

This chapter summarizes the means to be found faithful to God when Jesus appears to establish His kingdom upon the earth or when we are brought before Him in judgment, having left this earth before His return. It begins with acknowledging that some will not be faithful and fall away from the faith. These people will practice religion but do not truly know God or do His will. The faithful make priority the word of God in their lives. They nourish their souls with these words. These words develop our doctrine of God, so to truly know God well, we must know God’s word well. This is what it means to train ourselves in godliness. True godliness is obedience to God according to His word. Our spiritual training should be given no less time than our physical training, in which so many participate. This knowing of God’s words is to lead to action, the doing of God’s will. God has gifted us to serve Him so that we all work together to build His kingdom upon the earth as it is in heaven. The expectation of Jesus is upon His return to earth that He finds it reflecting His kingdom, for this is the work His church was left to do, teaching all men everywhere to obey everything Jesus commanded. This work should absorb our thinking and our actions. It is our life. To be focused on anything more significant than knowing Christ and making Christ known in the world is to risk falling away from Christ and failing to do God’s will by living as God’s people.
