Romans 4:20 KJV
He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
The promise given to Abraham was he would father nations. Humanly speaking, it was a ridiculous premiss. Both he and Sarah were well past childbearing age. But, strong faith disregards natural circumstances in favor of supernatural influence.
Romans 4:19 NLT
And Abraham's faith did not weaken, even though, at about 100 years of age, he figured his body was as good as dead—and so was Sarah's womb.
In a manner of speaking, the Lord has placed “nations” within us. Nations waiting to be birthed. Each of us has a holy cause—something bigger than ourselves that requires strong faith to accomplish.
Your top priority (and mine) is to develop your faith to bring forth your nation—your holy cause. The life of faith is a great adventure, with great rewards. Our allies are the Word of God and the Holy Spirit. Through faith we cannot fail to bring forth our nations.
