"But be doers of the word, and not hearers only, deceiving yourselves." (James 1:22 ESV)
Faith is acting on the Word. God's Word is all-powerful, it has the ability to produce in you what it talks about. Nonetheless, God's Word in you won't produce any result unless you ACT on it-- the Word mixed with faith is what produces results. What is faith? Simply put, it's the response of the human spirit to the Word of God.
Every time you hear God's Word, faith comes to your in the Word; and because the Word is more real in your spirit than in any physical circumstances, it propels you to take action. That's what Abraham did. He mixed the Word with faith-- he ACTED on what he heard. In Genesis 17:5, the Lord had said to him...
"...a father of many nations have I made thee..."
But at this time, Abraham was still childless. Then the Bible says Abraham believed God.
(Romans 4:17, 19-21)
"...God, who quickeneth the dead, and calleth those things which be not as though they were... And being not weak in faith, he considered not his own body now dea, when he was about an hundred years old, neither yet the deadness of Sarah's womb: he staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God..."
Could this be you? Could this be the description of your faith? It should, and must be. The Bible says we should be like this description in Hebrews 6:12--
"...followers of them who through faith and patience inherit the promises..."
So, just like Abraham, always create the right environment for the Word to produce results in your life. Mix with Word with faith. Refuse to consider physical circumstances. Refuse to stagger at the Word of God through unbelief. Yes, God's Word never fails, but the efficacy of God's Word in your life depends on your response to the Word. Therefore, take a stand on God's Word for yourself. Be a doer of the Word, and your progress, victories, and success will not only be evident, but also consistent.
At all times and in all seasons, irrespective of the circumstances or contrary situations, I choose the faith-way. I have the assurance on the basis of the Word that I'm who God says I am, I have what He says I have, and I can do anything He says I can do! My faith prevails today and always. Hallelujah!
