The Bible tells us that the disciples were ‘uneducated and untrained men, BUT they had been with Jesus’ Acts 4:13.
We may not be clever, or get good grades at school (always try your best), but we must spend time with Jesus in prayer and by reading the Bible. Then we will be like the disciples ‘who turned the world upside down’ Acts 17:6.
"...Whatever you do, do all for the glory of God." and "I planted, Apollos watered, but God gave the increase." 1 Corinthians 10:31 and 3:6.
Ask God to give you divine appointments with your friends and family to share the gospel. You can also pray for them regularly.
As you share the gospel, don't feel under pressure because it is God who enlightens the mind and soul as the 'Holy Spirit brings conviction of sin, judgement and righteousness.' John 16:8.
