For this is the message you heard from the beginning: We should love one another.
When Jesus was asked what is the greatest commandment He responded with two things: to love the Lord thy God with all thy heart, soul, mind, and strength, and to love your neighbor as yourself. He said the law and the prophets were summed up in these two statements. Christianity is simply about love. As we grow in Jesus Christ we naturally grow in His love.
As we draw near to the Lord each day we are transformed from the inside out. It is the work of the Holy Spirit within our hearts that transforms us. The Lord has called us to simply abide in Him each day and draw near. Following Jesus is not about hard work, but simply about growing in intimacy. Those who walk in deep intimacy with the Lord come to understand who they are in Christ. The enemy would want nothing more than to keep us from drawing near to the Lord, but the Lord has told us in His word to draw near to the throne of grace with confidence.
