ALL have sinned. Not just some of us, but ALL of us. The Bible says that that sin in all of us deserves punishment and justice. It says that we all deserve to die because of that sin.
That is why we ALL need Jesus because we ALL have sinned. Lucky us though, our God is forgiving and loving and merciful and he has given ALL of us a gift of salvations through Jesus Christ. We are weak ALL weak on our own and we will continue to fail, but through our failing God will show us His mercy and goodness.
When we are weak and we turn to God, we see just how strong he really is! We are ALL weak and broken and we ALL need Jesus! We cannot do this without him.
So let me ask you this: Do you see how broken you are? Do you know that you need salvation? Have you accepted the gift of eternal life through Jesus Christ?
