In Matthew 16, Jesus said to his disciples, "Whoever wishes to come after me must deny himself, take up his cross, and follow me." Of course, we are weak and cannot always perform as well as we'd like to, but it's our intention that matters. Back in Matthew 11, Jesus said, "Take my yoke upon you and learn from me, for I am meek and humble of heart; and you will find rest for yourselves. For my yoke is easy, and my burden light." So the Lord can lighten all our burdens. If we'll let him, we can be strong as we want! When we wish to serve him well, he will serve us well.
