Even when we walk with God a long time, fear is still an adversary, and old habits are hard to break. Abraham was protected by God despite that Abraham was still lying about Sarah. God's choosing is not based on us, it is based on His mercy and grace that He protects us. We do not earn God's favor or obtain our salvation by works. God is so gracious and merciful that God forgives us and takes us to Heaven, but He continues to use imperfect people for His glory. When God tells us something, we need to obey immediately. God deals with all kinds of people, when Abraham said there was no fear of God in the place, Abraham was wrong. God has written magnificent history and it is being played out all over the world. God has revealed Himself through His word and we would do well to believe HIm. If we use half-truths to deceive, we are lying and we do not want to be on Satan's team. God knows what He is doing and He has chosen to do what is best.
