Grace is divine enablement from God, which means God is giving you strength to do that which you cannot do with your ability.
That is why the Bible says that we can do all things through Christ who strengthens us. So, what grace does is that it helps boost our performance. (Philippians 4:13)
As humans, we all have our weaknesses but when we accept Jesus as our saviour, He gives us the power to overcome those weaknesses.
Therefore we overcome those weaknesses not because of our strength but because of the spirit and the power of God dealing with us.
That means that as Christians, God has given us the ability to overcome our weaknesses “My grace is sufficient for you”.
We need also to acknowledge our weaknesses and pray to God for help so that God can help us overcome those weaknesses.
