When you feel undeserving of Christ's grace, do you feel led to things that give you immediate satisfaction? You are right. We are undeserving of Christ's grace and could never earn it. Some faiths have their members give all their wealth and worldly belongings to the church, but Christ doesn't ask for that. Some faiths ask their members so shave their heads and sell flowers, etc. but Christ doesn't ask for that. We don't have to earn our salvation, because Christ already paid the price by giving His life on the cross for us and rising from the dead. We just have to believe in Him as our Savior. He would also like us to live as examples of our faith in Him by being fair and showing compassion to those in need even when it goes against the norm and having a humble Spirit in the Lord.
He hath shewed thee, O man, what is good; and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God? Micah 6:8
