But Nobody's Perfect!

Therefore you are to be perfect, as your heavenly Father is perfect. Matthew 5:48

Nobody's perfect. True. We are NOT perfect, but we ARE correctable. One of the purposes of Scripture is that of correction. If God did not intend for us to change He would not have provided for us Scripture that teaches, reproves, corrects, and trains.

All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work. 2 Timothy 3:16&17

Again, nobody's perfect so why try? We try because it's what God asks of us. Maybe I'll never understand or be able to explain why God created us fallible and then asks for perfection. Maybe that's just one of those mysteries that I'm happy to let God take care of. Maybe I'll just do my best and trust God's mercy and grace will take over where I fall short. Maybe this is God's way of illustrating that I cannot do it on my own. This asking us to be impossibly perfect forces us to rely wholly upon Him.

What shall we say then? Are we to continue in sin so that grace may
increase? May it never be! How shall we who died to sin still live in it? Or do
you not know that all of us who have been baptized into Christ Jesus have been
baptized into His death? Therefore we have been buried with Him through
baptism into death, so that as Christ was raised from the dead through the glory
of the Father, so we too might walk in newness of life. Romans 6:1-4

Clearly, our inability to be perfect is not license to sin. We are raised to a new life. A life in which we need to die to ourselves a little more each day. We just need to allow God to do His work in us and make us into the person he intended us to be all along.

But now, O LORD, You are our Father, We are the clay, and You our
potter; And all of us are the work of Your hand. Isaiah 64:8
