Galatians 5:17 For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish.
By our very nature we rebel against God. It is not something new and it will continue to be the fact until we all join Christ in Heaven!
Christ came to earth to fight the fight against evil so we could have eternal life even though we fight against Him to start with.
Just as we have many opposites in the physical world, light and dark, fire and water, so our lives are spiritually opposite to Christ’s until we trust Him to forgive us for all those things we do wrong.
We may want to do good things, but our sinful nature leads us astray much of the time!
