Grace is not something that comes naturally. It goes against human nature. To be sincere and transparent with grace you need to pray for it, through it, and accept it from God. Grace is getting something good when you do not deserve it, so giving grace can be hard. The person you choose to give grace to may not even be aware that they hurt you, care, or repentant.
The power of prayer can transform your life. Making prayers to be able to give grace is powerful. It will transform your heart even it the motivation never changes. It frees you to be able to love like Jesus. Jesus loved sacrificially and with a servant's heart. He taught up how to give of what we have and get more so you do not burn out or go empty yourself. Prayer and time with God is the key.
Grace will sustain you because it gave you your salvation. It helps you build your faith. With grace you can face your enemies and know that you are not alone. You understand that the Holy Spirit will put the words in your mouth as you need them. You understand that you are not perfect, but God is and you trust that. He lovingly gave you grace, so you want to at least try to give grace to other people. After all love covers all kinds of sin.
It is your prayer life that brings your salvation alive. Prayer along with Biblical study helps you leave your sinful nature behind. You won't do it perfectly, but you know you will not be alone. In your faith you became righteous through grace. You can do anything with Jesus by your side. You can even forgive the unforgiveable. You can give second chances when they are not deserved. You can have everything taken and know you will be okay. You can embrace how much you are loved and give grace to other people even if they do not love you. You can give grace because you are friends with God.
