Believers are not to speak, look, think, or act like the world. In every way possible, believers are to remain separate and distinct. Believers saved for any length of time have noticed the drastic shift in what the world defines as acceptable and unacceptable behaviour. For instance, man in general once disdained the idea of tattoos, body piercings, and cuttings in the flesh (Leviticus 19:28). Yet, now these things are not only acceptable but even practiced by believers. The world used to distinguish between men and women, even taking note of one’s hair length (1 Corinthians 11:14-15). Yet these distinctions have been blurred and in some cases eliminated with men attempting to become women and women men. The people of God are not to follow along with cultural shifts, but abide rather in the unchangeable words of God.
The Lord desired a special relationship with the nation of Israel choosing to bless them both spiritually and physically above all other nations. One such blessing involved bringing them safely into the land of Canaan. However, many of these blessings were dependent upon Israel maintaining the right type of relationship with the Lord. He, therefore, issued several commandments for the Israelites to carefully keep (i.e., Deuteronomy chapter 11). The Lord desired for Israel to “hearken diligently” (Deuteronomy 11:13) and “diligently keep” (Deuteronomy 11:22) these commandments. He wanted His people to carefully listen when He spoke, giving God their full attention (listening to every word). He also wanted them to attentively obey what they heard. He always desired for His people to listen to and obey Him. God speaks today through the Bible. He still wants men to diligently hear and obey.
A godly mother and grandmother helped raise Timothy by teaching him the truths of God’s word (2 Timothy 1:5; 2 Timothy 3:15). Paul wrote to Timothy specifically warning him in 1 Timothy chapter 4 concerning the dangers of the last days (i.e., the doctrines of devils, fables, and unedifying quarrels). In the midst of these warnings, Paul reminded Timothy to take heed unto himself. Timothy needed to guard against troubles from without while diligently taking care of his own walk with Christ. The Old Testament further reinforces these truths. The children of Israel were told to keep their souls diligently (Deuteronomy 4:9) and Solomon instructed his son to keep his heart “with all diligence” (Proverbs 4:23). Every Christian should carefully and zealously guard his walk with the Lord.
