Many people in the world profess a belief in the God of the bible, but do they really believe that He can and will do what He says He will do? It’s easy enough to say that we believe, but our actions will really “tell the tale”. Take, for example, the Isrealites of Moses’ day. You would be hard pressed to find any group of people who had more reason to believe in God and His power than they. They personally witnessed the plagues that God brought upon Egypt, they saw the Red Sea parted and walked across on dry land, they were fed with manna from heaven (Exodus 7-16), yet we are told in Hebrews 3:19 that they could not enter the promised land “because of unbelief”. They didn’t believe that God could do, or would do what He had said that He would do.
We have sufficient evidence today to believe in the God of the bible and His power. In John 20:31 John said that the things he had written were so that we “might believe and believing have life in His name.” In Romans 1:20 the apostle Paul writes that, “His eternal power and Godhead” are clearly seen from a study of the creation around us so that we are, “without excuse”. In spite of all the available evidence and in spite of their words, the actions of many people proclaim their unbelief. The author of Hebrews warns us that what happened to the Isrealites might also happen to us. We might not be able to enter God’s promised rest, “because of unbelief’ (Hebrews 3:12-19), if we don’t believe that God can and will do what He says He will do and act on that belief.
“Beware brethren, lest there be in any of you a heart of unbelief in departing from the living God; but exhort one another daily, while it is called ‘Today’, lest any of you be hardened through the deceitfulness of sin. For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end, while it is said: ‘Today, if you will hear His voice, do not harden your hearts as in the rebellion.’” Hebrews 3:12-15 NKJV
