When I became a Christian the summer before my sophomore year, I wasn't very outspoken about it at first. I showed my faith more through my actions. I knew I had to separate myself from that old lifestyle. So even though I kept in contact with my old friends, they weren't my main group of friends anymore. I spent almost two years growing in my faith and getting to the point where I knew I could be with my old friends and not be tempted to fall back into that old lifestyle.
Sin gets in the way.
Sin's like a big canyon that separates us from God. Sin is any action or attitude that goes against God's commands. Jesus Christ died for our sins. We can trust Jesus. When we do this, we receive God's grace and are saved from our sins.
