Profession of Faith 10.12.21
"Not everyone who calls out to me, 'Lord! Lord!' will enter the Kingdom of Heaven. Only those who actually do the will of my Father in heaven will enter."
It appears that when we die, God will look at our lives. Even those who profess faith will be evaluated to see if our lives prove we have genuine faith. True faith yields a desire and practice of obedience to the Lord.
Sadly many will tell you they are believers but live like they are not. Their faith is merely a facade. This profession may fool some people, but it will not fool the Lord.
If you believe and trust in the Lord, then follow Him! It's that simple.
