Who Can Be Against Us?

The bible says in Romans 4:19 "And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sarah's womb:" Abraham believed God, and it was counted unto him for righteousness (Romans 4:3).
Abraham had so much faith that all these factors did not persuade him to doubt God. Romans 4:21 "And being fully persuaded (convinced) that, what he (God) had promised, he (God) was able also to perform."
Romans 8:28 says "And we know that all things work together for good to them that love God, to them who are the called according to his purpose." Abraham knew that God was working for him on his behalf. He trusted God. That is why Abraham had so much faith in God because he knew God. He had a relationship with God and knew that God was an awesome, caring, and loving God. A God that worked things out for those whom loved him. Abraham also knew that when God made a promise, He would bring it to pass. God will not lie, He is bound by His Word.
Romans 8:31 "What shall we then say to these things? If God be for us, who can be against us?" Abraham did not consider his age or Sarah's barreness a factor in the promise of conceiving Isaac. God would bring this promise to pass as He had spoken. Abraham knew that God was for him. Nothing could come against Abraham with God on his side. The promise God made would come to pass and nothing could come against it or hinder it. Abraham's age couldn't be against him, and Sarah's barreness couldn't be against him.
When God makes us a promise in life, He will perform those things which He has promised. It may not be the way we want it to go or the way we THINK it should go but nevertheless God always delivers on what He says He will do. But we must trust and have faith that God is able to perform those things. God is looking for people who want all He has to offer. He is looking for people to bless. Everyday God is ready to pour His blessings out on His children. The bible says "the eyes of the Lord run to and fro throughout the whole earth, to shew himself strong in the behalf of them whose heart is perfect (at peace or loyal to) toward him." (2 Chr. 16:9)
God seeing the BIG picture knows all things. If we are trusting in God then we should be at peace. Not saying that worries will never arise but for the most part we should be at ease in our lives.
We should not let "factors" get in the way of what God has promised us. God does not go by our ability because we are not able to do anything without Him. God goes by availibility. The question God's asking each of us is, are you available? "Now unto him that is able to do exceeding abundantly above all that we ask or think..." (Ephesians 3:20)
God is able to do anything and able to do things that we cannot even imagine. God is bigger than we can grasp in our minds. And with Him on our side our problems are nothing for Him. That is why it is important for us to realize that nothing can stand against us when we have God for us. The storm, the mountains, our mouths, our bodies, and especially the enemy has no hold on us when it comes to Gods promises coming to pass.
