Grow in the grace and knowledge of our Lord and Savior Jesus Christ. (2 Pet 3:18) This does not appear to be an option. Once we enter the kingdom of God as little children, we are responsible for growing. We are not meant to sit on our salvation as a ticket to heaven and remain unchanged. In fact, if you do remain unchanged, it’s a good indication that you haven’t fully received salvation.
To fully understand that you have been saved by grace is to fall in love with the One who gave His life for you. That love draws you in, closer and closer. You want more of everything that He is. More love, more joy, more peace, and more grace.
Grace is God’s kindness and forgiveness. How do you get more grace? By being more kind and forgiving yourself. You have to lay down your own agendas and put others first. You have to hunger and thirst after righteousness. You have to want what God wants.
As you identify your own need for grace, you begin to receive more. Grace is attracted to humility. The more you know Him–having the knowledge of our Lord and Savior Jesus Christ–the more you grow in grace and the more kindness and forgiveness is yours from heaven.
