What if, i was living a lie? That everything i do is selfish?

Even then, “When we had no strength, at just the right time, Christ died for the ungodly.” – Romans 5:6

i may be a liar, but God is truth. Please trust in Him alone. Trust also, that since He has given you His Spirit and a new heart, that you too can choose to stop living selfishly and choose to follow Christ.
