Something happened between Genesis 15 to Genesis 21. Abraham and Sarah deviated from God’s promise. They took matters into their own hands to fulfill it. Their fleshly choice still bears the consequential fruit in our day ~ Ishmael’s descendants.
There is so much to this part of their lives that reflects our own when we step in to ‘help’ the Lord fulfill what He has spoken. It is in satan’s master plan to be sure that we derail and miss God’s promises.
God’s plan is stated countless times in Scripture. Ephesians 1:4 says that He chose us before time began to be holy and blameless. His plan will be fulfilled as stated in Jude verse 24. It says, “Now to Him who is able to keep you from stumbling, and to present you faultless before the presence of His glory with exceeding joy.”
No matter what our adverse circumstances are, nor the consequences we bear because of our disobedience, Philippians 1:6 will always hold true. It says, “Being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ.”
