Romans 1:17 (New International Version)   For in the gospel the righteousness of God is revealed-a righteousness that is by faith from first to last, just as it is written: "The righteous will live by faith. The Bible tells us that God is faithful to us and we must be faithful to him if we want to please him (Hebrews 11:6 And without faith it is impossible to please God,) and also gives us the definition of that faith at Hebrews 11:1 (Now faith is being sure of what we hope for and certain of what we do not see.)  We don't need a high IQ or to be someone special to have faith in God, and a small simple faith is enough to please him. Getting this across to people was one of the problems the Apostle Paul had as he traveled around telling people that Jesus Christ was their Savior (Acts 15:5 Then some of the believers who belonged to the party of the Pharisees stood up and said, “The Gentiles must be circumcised and required to keep the law of Moses.”.)  The Pharisees were the dominant and very strict in matters of the law Jewish denomination during Paul's time, and he encountered them almost everywhere he went. The Pharisees rejected Christ and were teaching people that they had to obey the old testament law in order to be saved. It was unbelievable to them that Christ had fulfilled the law for everyone, and faith in him was now all that was needed. We can try to obey the old testament law all we want but it will do us no good without faith in Christ (Romans 3:28  For we maintain that a person is justified by faith apart from the works of the law.)                   What About Jesus?                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 Footnote - I find it interesting that the NIV translation of the Bible uses the word faith (or a form of it such as faithful) about 450 times, and sometimes uses the word "obedient" for the word "faithful."

Matthew 18:2-3  He called a little child to him, and placed the child among them. And he said: "Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven. - When our daughter was learning to walk, she tried to go down some stairs one time, but I was holding onto her hands and we managed to avoid them. She could hardly walk on a smooth floor, but because I was there and holding on to her, she was certain that she could go down those stairs because she had faith in me that no harm would come to her. Christ uses the faith and humility of little children to illustrate what our attitudes toward God should be. Us grown up people like to apply common sense to everything, and common sense is a blessing from God that certainly has its place and I use it all the time. But little children, although often lacking common sense, have a humility and a faith that they can do things they wouldn't normally do if someone they trust is looking out for them. This what Christ is talking about in Matthew 18:2-3. Our "common sense" doesn't interest him in this case,he demands that we become childlike (not childish.) We must have the humility and faith of little children, and accept what God tells us, in order to enter the kingdom of heaven.    What About Jesus?
