In Exodus 3:7-10, God chose Moses to deliver the Israelites from Egyptian bondage and lead them to the land that He had promised. He said in v. 10, “Come now therefore, and I will send thee unto Pharaoh, that thou mayest bring forth my people the children of Israel out of Egypt.” Throughout the book of Exodus, we read of Moses’ obedience to God. He not only led the people, but also gave them the law God wanted them to live by. The Hebrew writer declared, “And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after” (Hebrews 3:5).
However, in Numbers 20:12-13, it is recorded that Moses did not follow God’s instructions and did not glorify God before the Israelites at Meribah (cp. Psalm 106:33). Because of this, Moses was told, “Because ye believed me not, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them” (v. 12).
We need to live right or we might lose our chance to go to heaven. Hymenaeus and Alexander had made shipwreck of their faith (1 Timothy 1:19). Hymenaeus and Philetus had overthrown the faith of some (2 Timothy 2:18). In the “latter times” (which means now), there will be some who will “depart from the faith” (1 Timothy 4:1). In 1 Timothy 5:12, the younger widows had “cast off their first faith.” While is true that some may fall away who was never sincerely committed as believers, there are many in the Bible who do not fall into this category. Don’t be led astray by people today who tell you it is impossible to fall. It WAS possible in the Old Testament and it IS possible today!
